Assume that you have a sample of n1=9​, with the sample mean X1=42​, 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 =36​, and the sample standard deviation S2=6. Construct a 95​% confidence interval estimate of the population mean difference between μ1 and μ2.
