Resting Heart Rates of American Adults
A normal resting heart rate for adults ranges from 60 to 100 beats a minute, reports Dr. Edward Laskowski of the Mayo Clinic. Lower resting heart rates are generally associated with higher cardiovascular fitness. With the marked increase in obesity in America, there is rising concern that the average resting heart rate of American adults is trending towards the higher end of the accepted range. A recent study conducted by the Statistical Health Association of America validates this concern. Results were based on a sample of 1587 American adults (ages 18 and older). The mean resting heart rate from this sample was calculated at 87 beats per minute (bpm). The study concludes, with 95% confidence, that the true mean resting heart rate of American adults is in the interval (80, 94).
1. (1 point) What is the population that the confidence interval in the article is making an inference about? Be specific.
2. (1 point) What is the parameter of interest for the confidence interval in context?
3. (2 points) Give the confidence interval as reported in the article. Is the reported interval in the form of an interval or is it in the form of estimate ± margin of error? If it is not in interval form, give it in interval form.
4. (2 points) What confidence level is associated with the given interval? Is the choice of confidence level reasonable? Why or why not?
5. (2 points) Interpret the confidence LEVEL given in your previous answer in your previous answer in the context of the problem.
6. (2 points) How was the sample collected? Does this allow us to infer things about the population? If the article does not state how it was collected, how SHOULD it have been collected?

Security plan -privacy policies- risk assessments
Part 1 Devils Canyon
Part A: Ch. 3 Role Playing Sim: Devils Canyon
In this simulation, you will evaluate how to design an enterprise architecture for a Mountain Resort. Your job is to utilize the teams vision to design the enterprise architecture using the interactive map tools while staying within budget. Using the Devils Canyon Simulation Access link, complete the interactive before moving to Part B.
Part B: Policies, Plans, and Risks
Now that youve seen all of the elements contributing to the Devils Canyon enterprise architecture, Justin wants to move forward with developing privacy policies to ensure videos arent distributed or uploaded to the net without the consent of the people in them. This opens a much larger conversation: Devils Canyon is also in need of a complete security plan, as well as risk assessments.
In a 3- to 4-page rationale and table, prepare the following information to present to the Devils Canyon team:
Explain the relationship between policies and security plans. Identify potential policy needs, noting Justins privacy policy, in relation to the Devils Canyon enterprise structure.
Outline the importance of a security plan in relation to security roles and safeguards.
Analyze at least 5 security-related risks/threats that Devils Canyon may face.
Assess the probability and impact to the Devils Canyon if each risk occurs. Based on these two factors, determine the overall risk level. For purposes of this assignment, evaluate and categorize each factor as low, medium, or high, and create a table to illustrate the risks. For example, a risk/threat with a low likelihood of occurrence and a high impact would represent an overall medium risk.
Consider digital elements mentioned in the designing of the enterprise architecture, such as software, hardware, proposed security measures, smart lift tickets, webcam systems, and smartphones.
Part 2 Devils Canyon
Using the potential risks for Devils Canyon you identified in Part 1, create a 4- to 5-page matrix to share with the team. In your matrix, you should do the following:
Describe briefly each of the identified risks/threats.
Evaluate the security controls that mitigate each of the risks/threats identified.
Provide a rationale for how each of the controls identified mitigates the risk to an acceptable level.
Research and describe the security technologies and security design that can be used to mitigate each of the identified information security risks.

40. Techware Incorporated is considering the introduction of two new software products to the market. In particular, the company has four options regarding these two proposed products: introduce neither product, introduce product 1 only, introduce product 2 only, or introduce both products. Research and development costs for products 1 and 2 are $180.000 and $150,000, respectively. Note that the first option entails no costs because research and development efforts have not yet begun. The success of these software products depends on the trend of the national economy in the coming year and on the consumers reaction to these products. The companys revenues earned by introducing product 1 only, product 2 only, or both products in various states of the national economy are given in the table below. The probabilities of observing a strong, fair, and weak trend in the national economy in the coming year are 0.30, 0.50, and 0.20, respectively.a. Formulate a payoff table that specifies Techwares net revenue (in dollars) for each possible decision and each outcome with respect to the trend in the national economy.b. Use Precision Tree to identify the strategy that maximizes Techwares expected net revenue from the given marketing opportunities.c. Perform a sensitivity analysis on the optimal decision, letting each of the inputs vary one at a time plus or minus 25% from its base value, and summarize your findings. In response to which model inputs is the expected net revenue most sensitive?
ITS 3110 Savannah Applied System Alnalysis Identifying Requirements Paper
Mobile technologies represent a significant part of today’s software market. Their pervasive nature enables experienced, as well as inexperienced, users to interact with them for accomplishing a particular task. In addition, the diffusion of the computing systems on which they run, such as smartphones or tablets, coupled with an intertwined retail method (application stores present on all devices), allows for a capillary distribution of such applications.For this project, assume you are a programmer analyst. You are required to identify an organization, and then utilize the knowledge acquired in the course to simulate the creation of a mobile application that your company will be able to sell to the organization. Based on the description of the organization (you may get this from their website or directly from the personnel), you should identify a possible application that may be of interest to them. The application should contain different features, including data-driven material that should be available within the application itself, without having to rely on external data sources.For example, you select a large sports goods company and decide to create a customer-guidance application for the company. The application should offer an interface where customers could type in what they are looking for to be guided through the store leading them to the right department or section. The application should also enable the customers to watch video demonstrations of the products available in the store, after they scan the product barcode by using a camera. Moreover, the application should be able to suggest places in the store vicinity where customers may try certain items; for example, the application may guide the customers to archery ranges if they are interested in bows and arrows. Perhaps, you could add a feature that suggests apparel to the customers based on their lifestyle and something they can easily purchase through the device, without needing to go to the store.You could use Microsoft PowerPoint or Visio for creating these diagrams. You should assume that the project could be handled in-house, therefore, no outsourcing should be considered through the project. This week, complete the following tasks in a 2- to 3-page Microsoft Word document:Provide an in-depth description of the company..Provide a list of all the potential stakeholders of this project. Justify your selection of stakeholders.Provide a complete statement of work.
IU Communications Visual Aids Assist the Speaker Discussion
Using Presentation Aids to Enhance Your Speech BACKGROUNDPresentations are used for a variety of purposes. Most often, they are used to inform, teach, report, advertise, persuade, or inspire audience. Depending to the purpose of a presentation, its content, structure, and design may differ.Purpose of informative presentations is to inform about events or demonstrate some products, services, or product functions. While teaching presentations demonstrate how to do certain things: operate a device/tool or implement new process. Reporting presentations, on the other hand, convey status report of a project or process.Other common types of presentation in a business field are those that advertise, persuade, or inspire audience. Presentations focused on advertising target sales of products of services; persuasive presentations engage auditorium in decision making, while inspiring presentations engage into problem solving.When type and purpose of presentation are selected, presentation slides need to be designed with that purpose in mind. Slide design approach known as assertion-evidence (AE), is often used in the professional field. What is AE approach? Alley (n.d.) provides a clear outline of what AE approach is:This approach will help you to create better understood presentations, as evidenced by tests of audience comprehension. In addition, the approach will make your presentations more focused and help you to project more confidence.In the assertion-evidence approach, you build your talk on messages (not topics) to tell a coherent and compelling story about your work. Those messages you then support with visual evidence (not bullet lists). In addition, you engage the audience by fashioning sentences on the spot, but after practice.Presentations often contain visual elements that help to communicate a message or idea with less words. Those different visual elements are called presentation aids. Presentation aids include but are not limited to images/photographs, charts, tables, graphs, videos, audios, and special visual effects like animation.Before you proceed with this assignment, please review the following videos that give excellent information about how to use other types of aids during your speech:Video #1: Using Visual Aid Part 1Video #2: Using Visual Aid Part 2Alle, M. (n.d.) Assertion-Evidence Approach. Retrieved form Part 1: After researching and reviewing the various types of presentation aids, decide which would be best-suited to add to the speech you gave last week. Justify your choice in one paragraph.Part 2: Reflect on your experiences in this class.
University of Prince Edward Island Child Abuse and Family Violence Paper
Explore the vignette and identify the type(s) of abuse, indicators of abuse, possible cause(s) of the abuse, the possible long-term effects of abuse, and the appropriate fashion in which this case should be handled by a mandated reporter. This should be 4 to 5 pages long and have a cover page, abstract, and reference page, which do not count towards the 4 to 5 pages. Use your text to properly reference all key terms and ideas related to your case investigation. It should be in APA format, so see the guide uploaded under course materials for assistance. Vignette: Jasmine is a 14-year-old African American girl in the 9th grade. She lives at home with her mother and has no contact or information on the identity and whereabouts of her father. Her mother dates frequently and Jasmine has been exposed to several men. Jasmine is having some difficulty with school work and it may be because she is frequently tardy for school and sleepy or sluggish when she arrives. She and her mother argue and even physically fight at home, which has made it difficult for her to keep up with her schoolwork. When she was younger she and her mother got along very well, but once Jasmine started middle school, she became moody and her mother’s current boyfriend moved into the home. Jasmine does not care for him either. She feels that he is very controlling and is constantly trying to tell her what to do. This has particularly caused a problem lately because Jasmine has her first boyfriend, Davian. Davian is one of the more social guys at her high school. He is in the 10th grade, but he has been retained twice so he is 17 years old. He is constantly surrounded by his peers, particularly other girls. Davian is used to getting his way and can be somewhat forceful in their relationship. Teachers have talked to him on several occasions about being too aggressive with Jasmine (ie., grabbing her in the halfway or yelling at her when he is angry). Jasmine is tired her issues at home and school, but sometimes her relationship stresses her out too. She feels the need to be a “ride or die chick” for Davian, but she sometimes wants to talk to the school guidance counselor about all the issues she experiences with him.

But I do know that they need to have more on campus then ever before. I think that the state needs to make sure that we are safe at schools. I do not think that it should be left in the hands of our kids or teachers to carry. Our teachers have a job to do and thats to teach and to make sure that our kids feel that they can talk to them and help them with there homework amongst other duties they have. But in no way shape or form should teachers carry. Its not there job. Its the Police officers. The Federal commissioners , The President needs to issue out more funds to keep schools safe. Its not our teachers responsibility. Let them solely focus on our childrens education and let the Police do the protecting. Just like they do on premises with the white house – they have guards everywhere. Why cant the schools get what they need.
