Problem 93SE

Two independent random samples are taken from two populations. The results of these samples are summarized in the following table:

a. Form a 90% confidence interval for (μ1 – μ2).

b. Test H0: (μ1 – μ2) = 0 against Use α = .01.

c. What sample size would be required if you wish to estimate (m1 - m2) to within .2 with 90% confidence? Assume that n1 = n2.

 Sample 1 Sample 2 n1 = 135  = 12.2 s21= 2.1 n2 = 148  = 8.3 s22= 3.0
