10.165 Design your own study involving two populations.

a. Determine a set of questions that compare the means, proportions, or variances of two populations of interest to you. You might consider two different class levels as the two populations and questions similar to the following: Is there is a difference between their mean cost of books and supplies for a semester? Is there is a difference between the proportion of those with credit cards of their own? Is there is a difference between the proportion of those with four or more credit cards of their own?

b. Define two specific populations that you will sample, describe your sampling plan, and collect the data needed to answer your questions.

c. Discuss any differences and similarities between your study and the Chapter Case Study.
