Consider the following hypothesis test.

H0: μ = 20

Ha: μ ≠ 20

A sample of 230 items will be taken and the population standard deviation is σ = 10. Use α = 0.05. Compute the probability of making a type II error if the population mean is the following. (Round your answers to four decimal places. If it is not possible to commit a type II error enter NOT POSSIBLE.)

(a) μ = 18.0

(b) μ = 22.5

(c) μ = 21.0
