Use at-distribution to find a confidence interval for the difference in meansd=1-2

using 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 usingd=x1-x2

.

Best estimate = 4.6

A99%confidence interval ford

using the paired data in the following table:

Case 1, 2, 3, 4, 5

Treatment 1 23 29 32 25 28

Treatment 2 17 31 24 21 21

Give the margin of error and the confidence interval.

Enter the exact answer for the best estimate, and round your answers for the margin of error and the confidence interval to two decimal places.

margin of error =

Enter your answer; margin of error

The99%confidence interval is__________ to __________
