Question:

Consider again the conditions of Exercise 2. Let μ1 denote the mean of each observation for drug A, and let μ2 denote the mean of each observation for drug B. It is assumed, as in Exercise 2, that all the observations have a common unknown variance. Use the results of Exercise 6 to construct a confidence interval for μ1 − μ2 with confidence coefficient 0.90.
