What evidence, if any, supports the claim that 30 dollars/day is insufficient to cover all three meals?

For most of this class, you have been working with the following situation:

ABC Enterprises is a growing company in which employees must frequently travel for business. Currently, each employee is allotted 30 dollars each day to cover all meals. Employees have complained that this is not enough, especially when traveling to some of the more costly cities and countries. A survey was taken to get recommendations for a new allotment. Although not all responded, the response rate was good.

• What evidence, if any, supports the claim that 30 dollars/day is insufficient to cover all three meals?
• Why can’t we just use the sample data and say it’s the same as the population data? Why did we have to make confidence intervals and do hypothesis tests?
• Why is organization of data essential in statistics?
• What kinds of skills that you needed/learned in this class would you be able to use in a business situation in your field?
