Conduct a TOWS analysis of your client’s website.
Conduct a TOWS analysis of your client’s website. Your analysis should be specific to e-commerce / online aspects of the client’s business. If you are making any observations based on external sources / research (for example about opportunities) make sure to properly reference the source(s).
Explain the concept of the long tail principle in e-commerce.
Explain the concept of the long tail principle in e-commerce. Discuss why it is important. Describe how it can be applied in various ways in any e-commerce project. Make sure to reference your sources (at least five) in APA style.
Implement a controller called ‘Lab1_Task3.py’.
Implement a controller called ‘Lab1_Task3.py’. The program should make the robot follow the
path shown in Figure 4 in a clockwise direction. The trapezoid has length “H”, top width “W”,
and internal angles “a” and “b”. Robot should start at (0, H/2) moving counterclockwise. After
completing the trapezoid, the robot should stop. The full motion must be completed in a
maximum of “Y” seconds, moving at the same constant speed “X” inch per sec, except when
turning at the corners. Note that the robot may stop based on time or encoder readings. If the
motion cannot be completed for any given reason, the robot should display an appropriate
message. The TA will test for different values for “H”, “W”, “a”, “b”, “X” and “Y”.

Implement a controller called ‘Lab1_Task1.py’.
Implement a controller called ‘Lab1_Task1.py’. The robot should move in a straight line for “X”
inches at constant velocity. The robot should use the kinematics formulas to move for “X” inches
in “Y” secs and stop based on time, not on readings from position sensors. If the robot cannot
complete the movement in the given amount of time, instead of moving forward, the program
should display an appropriate message. Provide a plot, showing “Distance” vs. “Time”. Distance
should be computed from PositionSensor readings. You can write this data into a file from your
Python console as the simulation runs. During evaluation, the TA will test different values for
“X” and “Y”.

Consider the following OLS regression line obtained from a
random sample of 500 workers: = 0.3 + 0.1 educ +
0.005 exper + 0.02 tenure (1), where wage is hourly wage
(measured in dollars), educ is years of formal education, exper is
years of labor market experience and tenure is years with the
current employer.
Consider the following OLS regression line obtained from a
random sample of 500 workers: = 0.3 + 0.1 educ +
0.005 exper + 0.02 tenure (1), where wage is hourly wage
(measured in dollars), educ is years of formal education, exper is
years of labor market experience and tenure is years with the
current employer. Which of the following statements is correct?
According to equation (1), the predicted log(wage), when
educ = 0, exper = 0 and tenure = 0, is 0.3—which is not
meaningful.
According to equation (1), holding exper and tenure fixed,
another year of education is predicted to increase wage by
10%.
According to equation (1), if we choose two workers, A and
B, and these workers have the same levels of experience
and job tenure, but Worker A has one more year of formal
education than Worker B, then we predict Worker A to have
Consider the following OLS regression lines obtained from a random sample of 200 students: = 2 + 0.03ACT (1) and= 2 + 0.01ACT + 0.5 hsGPA (2), where colGPA is college grade point average, hsGPA is high school GPA and ACT is achievement test score.
Consider the following OLS regression lines obtained from a
random sample of 200 students: = 2 + 0.03ACT (1) and
= 2 + 0.01ACT + 0.5 hsGPA (2), where colGPA is college
grade point average, hsGPA is high school GPA and ACT is
achievement test score. Both colGPA and hsGPA are on a fourpoint scale. ACT are tests taken by students when they were in
high school, to assess their readiness to attend college. Which of
the following statements is correct?
According to equation (1), an increase in ACT score by 10
points is predicted to increase colGPA by 0.03 point.
According to equation (1), an increase in ACT score by 10
points is predicted to increase colGPA by 0.3 point, holding
hsGPA fixed.
According to equation (1), an increase in ACT score by 10
points is predicted to increase colGPA by 0.3 point.
According to equation (1), an increase in ACT score by 10
points is predicted to increase colGPA by 0.03 point,
holding hsGPA fixed.
Using the data from Table 1, and based on your OLS estimation of model (1) using Data Analysis tool in Excel, you can predict that an increase of an ACT score by 5, evaluated at the ACT = 20, will lead to an increase in college GPA by [ΔGPA].
Refer to Table 1. Table 1 contains the ACT scores and the GPA
(grade point average) for eight college students. ACT tests were
taken by students when they were in high school, to assess their
readiness to attend college. GPA are students’ grades once in
college; GPA is based on a four-point scale and has been
rounded to one digit after the decimal. Consider the simple
model: GPA = β0 + β1ACT ½ + u (1). Using the data from Table 1,
and based on your OLS estimation of model (1) using Data
Analysis tool in Excel, you can predict that an increase of an ACT
score by 5, evaluated at the ACT = 20, will lead to an increase in
college GPA by [ΔGPA].
NOTE: In model (1), ACT is to the power ½. Please write your
answer in number format, with ONLY 1 decimal place of
precision level; do not write your answer as a fraction. Add a
leading minus sign symbol, a leading zero and trailing zeros when
needed. Use a period for the decimal separator and a comma to
separate groups of thousands.
