4. (This problem is required to submit) Consider the following hypothesis test.
H:µ = 20
H.:µ + 20
A sample of 200 items will be taken and the population standard deviation is o = 10. Use a = 0.05.
Compute the probability of making a Type II error if the population mean is:
a. u =18.0 (33%) (Note: without calculation process, no credit)
b. µ= 22.5(33%) (Note: without calculation process, no credit)
c. µ=21.0 (34%) (Note: without calculation process, no credit)
