Use a T-table if necessary.

Use a t-distribution to find a confidence interval for the difference in means ua = H, - Hz 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 using d = x1 – x2.
A 99% confidence interval for ua using the paired data in the following table:
