Interpret P (Type II error): for a test of Ho: u = 0 against Ha: u > 0 based on n = 30 observations and using a(greek letter alpha) = 0.05 significance level, P(Type II error) = 0.36 at u=4. Identify the response that is incorrect. (a) at u=5, P(Type II error) < 0.36. (b) if a(greek letter alpha) = 0.01, then at u = 4, P(Type II error) > 0.36. (c) if n=50, then at u=4, P(Type II error) > 0.36. (d) the power of the test is 0.64 at u = 4. Solution (c) if n=50, then at u=4, P(Type II error) > 0.36.
