For the test at level 0.05 of the hypotheses given by (4.6.1) with 0 = 30,000
Question:
For the test at level 0.05 of the hypotheses given by (4.6.1) with μ0 = 30,000 and n = 20, obtain the power function, (use σ = 5000). Evaluate the power function for the following values: μ = 25,000; 27,500; 30,000; 32,500; and 35,000. Then sketch this power function and see if it agrees with Figure 4.6.1.
