Question:

Consider the following hypothesis test.

H0:

Ha:

μ 10

μ 10 The sample size is 120 and the population standard deviation is assumed known with σ 5.

Use α .05.

a. If the population mean is 9, what is the probability that the sample mean leads to the conclusion do not reject H0?

b. What type of error would be made if the actual population mean is 9 and we conclude that H0: μ 10 is true?

c. What is the probability of making a Type II error if the actual population mean is 8?
