Consider the following data from two independent samples with equal population variances. Construct a 98​% confidence interval to estimate the difference in population means. Assume the population variances are equal and that the populations are normally distributed.

x1=37.9 x2=32.9

s1=8.7 s2=9.2

n1=15 n2=16
