# Question

The following two samples were collected as matched pairs:

a. State the null and alternative hypotheses to test if the population represented by Sample 1 has a mean that is 2.0 units higher than the population represented by Sample 2.

b. Calculate the appropriate test statistic and interpret the results of the hypothesis test using α = 0.10.

c. Approximate the p value using Table 5 in Appendix A and interpret the result.

d. Verify your results using Excel’s Data Analysis. Mac users can rely on PHStat for this procedure.

e. Identify the p value from Excel and interpret the result.

f. What assumptions need to be made in order to perform this procedure?
