1) Calculate the appropriate t-statistic for the means presented in Table 1.

2) What additional information would you need to calculate t for Table 2?

3) Create a research question for which it would be appropriate to use the test of mean differencedependent samples. What are the null and research hypotheses?

4) Create a research question for which it would be appropriate to use the test of mean differenceindependent samples. What are the null and research hypotheses?

5) What is the main difference in calculations for mean differenceindependent samples when the variances are equal and the variances are unequal?

6) Create a research question for which it would be appropriate to use the test of proportion difference. What are the null and research hypotheses?

7) Professor Brown is interested to see if the graduating seniors in her sociology class have higher or lower college GPAs compared to their respective high school GPAs.
