Chapter 6, Section 4-CI, Exercise 188
Use the t-distribution to find a confidence interval for a difference in means H1 - H2 given the relevant sample results. Give the best estimate for 41 -H2, the margin of error, and the confidence
Interval. Assume the results come from random samples from populations that are approximately normally distributed.
A 99% confidence interval for u - H2 using the sample results X, = 79.1, s = 9.7, n = 25 and X2 = 61.6, s2 = 8.0, n2 = 20
