For a test of H 0 : = 0 against H a : > 0
Question:
For a test of H0: μ = 0 against Ha: μ > 0 based on n = 30 observations and using a = 0.05 significance level, P(Type II error) = 0.36 at μ = 4. Identify the response that is incorrect.
a. At μ = 5, P(Type II error) < 0.36.
b. If α = 0.01, then at μ = 4, P(Type II error) > 0.36.
c. If n = 50, then at μ = 4, P(Type II error) > 0.36.
d. The power of the test is 0.64 at μ = 4.
