Use a-distribution to find a confidence interval for the difference in means u1 - u2using the relevant sample results from paired data. Assume the results come from random samples from populations that are approximately normally distributed, and that differences are computed using d = x1 - x2.

A 99% confidence interval foru1 - u2using the paired data in the following table:

Case	1	2	3	4	5
Treatment 1	22	29	31	26	29
Treatment 2	19	30	25	21	21

best estimate =

margin of error =

The99%confidence interval is ? to ?
