answer part 3

Extracted text: Suppose you perform the hypothesis test Ho: µ = 90 versus H1: µ > 90. The population variance, o, is unknown. The sample size is n = 6. Assume the significance level is 0.01. Part 1: 1) Should you use z or t to find the critical value? Oz t Part 2 of 4 Part 2: 2) Choose the correct critical region.
