1. In which comparisons in Exercises 1–3 did you find a difference in weight gains? Write a summary of your findings.

2. Construct a 95% confidence interval for m1 - m2, where m1 is the mean weight gain in the normal protein group and m2 is the mean weight gain in the high protein group. Assume the populations are normally distributed and the population variances are equal. (See Extending Concepts in Section 8.2 Exercises.)
