Given two independent random samples with the following results:

n1=16 x‾1=128 s1=20   

n2=8 x‾2=99 s2=19

use this data to find the 90% 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.

step 1 of 3: find the point estimate that should be used in constructing the confidence interval.

step 2 of 3: find the margin of error to be used in constructing the confidence interval. round your answer to six decimal places.

step 3 of 3: construct the 90% confidence interval. round your answers to the nearest whole number.
