Given two independent random samples with the following results:

n1=12x‾1=73s1=27

   n2=12x‾2=102s2=22

Use this data to find the 95%

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