Simulation. Use a computer to generate n = 5 observations from the Normal distribution N(20, 5). Test H0 : μ = 20 versus Ha : μ = 20 at the α = 0.05 significance level. Repeat this process 100 times and then count the number of times that you reject H0. Explain your results.

6.130 Simulation. Use the same procedure for generating data as in the previous exercise. Now test the null hypothesis that

μ = 22.5. Explain your results.
