Question

a. What is a for the test procedure that rejects H0 if z = - 1.28?
b. If the test procedure of Part (a) is used, calculate b when µ = 9.8, and interpret this error probability.
c. Without doing any calculation, explain how b when m = 9.5 compares to b when µ = 9.8. Then check your assertion by computing b when µ = 9.5.
d. What is the power of the test when µ = 9.8? when µ = 9.5?
