Given two independent random samples with the following results:
n1=5 n2=8
x‾1=198 x‾2=182
s1=26 s2=23
Use this data to find the 99% confidence interval for the true difference between the population means. Assume that the population variances are not equal and that the two populations are normally distributed.
