Consider the following data from two independent samples with equal population variances. Construct a 95% confidence interval to estimate the difference in population means. Assume the population variances are equal and that the populations are normally distributed.

= 37.2 si = 8.9 ni-15 2 32.5 s, = 9.3 n2-16

= 37.2 si = 8.9 ni-15 2 32.5 s, = 9.3 n2-16 0
