Assume that you have a sample of n1=7​, with the sample
mean X1=43​, and a sample standard deviation of S1=5​, and you have
an independent sample of n2=17 from another population with a
sample mean of
X2=30​, and the sample standard deviation S2=6.
Construct a 95​% confidence interval estimate of the population
mean difference between μ1 and μ2. Assume that the two population
variances are equal.
