Assume that you have a sample of n, =7, with the sample mean X, = 50, and a sample standard deviation of S, = 5, and you have an independent sample of n2 = 15 from another population with a sample mean of X, = 36, and the sample standard deviation S, = 8. Construct a 95% confidence interval estimate of the population mean difference between u, and u2. Assume that the two population variances are equal.
