A decision is planned in a test of H0: = 0 against Ha: > 0,

A decision is planned in a test of H0: μ = 0 against Ha: μ > 0, using α = 0.05.

If μ = 5, P(Type II error) =

0.17.

(a) Explain the meaning of this last sentence.

(b) If the test used α = 0.01, would P(Type II error) be less than, equal to, or greater than 0.17? Explain.

(c) If μ = 10, would P(Type II error) be less than, equal to, or greater than 0.17? Explain.
