Question:

Suppose you want to determine whether the average values for populations 1 and 2 are different, and you randomly gather the following data.

(a) Test your conjecture, using a probability of 0.01 of committing a Type I error. Assume that the population variances are the same and x is normally distributed in both populations.

(b) Use these data to construct a 98% confidence interval for the difference between the two population means.
