Step 2 of 3 :  

Find the margin of error to be used in constructing the confidence interval. Round your answer to six decimal places.

Given two independent random samples with the following results: nį = 13 n2 = 15 x1 142 x2 122 S1 = 17 S2 = 32 Use this data to find the 80 % 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.
