Given two independent random samples with the following results:

n1=9x‾1=92s1=24n1=9x‾1=92s1=24   n2=14x‾2=130s2=31n2=14x‾2=130s2=31

Use this data to find the 80%80% confidence interval for the true difference between the population means. Assume that the population variances are equal and that the two populations are normally distributed.
