Given two independent random samples with the following results:

n1=8 x‾1=166 s1=28 n2=12 x‾2=194 s2=25

Use this data to find the 90% 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.
