Question:

Refer to Exercise 5.49.
a. Display the rejection region for an α = .01 test that the population median is greater than 40 using the large- sample approximation.
b. Compare the rejection region from Exercise 5.49 to the rejection region in part (a). Provide reasons for the differences in the two regions.
In exercise
A researcher selects a random sample of 25 units from a population. Let M be the population median. Display the rejection region for an α = .01 test that the population median is greater than 40.
