Question:
Given the two hypotheses
H0: μ = 400
H1: μ = 415
and σ2 = 1000 (for both hypotheses):
(a) Draw the distribution of e under both hypotheses.
(b) If the decision rule is chosen to be: reject H0 if e ≥ 410 from a sample of size 40, find the probability of a Type II error and the power of the test.
(c) What happens to these answers as the sample size is increased? Draw a diagram to illustrate.
