Chapter 10.3, Problem 76E
In each of Exercises 10.73–10.78, we have provided summary statistics for independent simple random samples from two populations. In each case, use the nonpooled t-test and the nonpooled t-interval procedure to conduct the required hypothesis test and obtain the specified confidence interval.
10.76
- a. Left-tailed test, ・ = 0.05
- b. 90% confidence interval
