Assume that you have a sample of n1=8, with the sample mean X1=46, and a sample standard deviation of S1=6, and you have an independent sample of n2=14 from another population with a sample mean of X2=36, and the sample standard deviation S2=8. Construct a 95% confidence interval estimate of the population mean difference between 1 and 2. Assume that the two population variances are equal. 12 (Round to two decimal places as needed.)
