For constructing a 95% confidence interval estimate for the difference between the means of two normally distributed populations,where the unknown population variances are assumed not to be equal,the summary statistics computed from two independent samples are as follows:
n1 = 50,
1 = 175,s1 = 18.5,n2 = 42,
2 = 158,and s2 = 32.4
-What is the upper confidence limit of the 95% confidence interval for the difference between the means?
