Applet Exercise Refer to Exercise 10.10. Click the button Clear Summary to delete the results of any previous simulations. Change the sample size for each simulation to n = 30 and set up the applet to simulate testing H0 : p = .4 versus Ha : p > .4 at the .05 level of significance. a Click the button Clear Summary to erase the results or any previous simulations. Set the real value of p to .4 and implement at least 200 simulations. What is the percentage simulated tests that result in rejecting the null hypothesis? Does the test work as you expected? b Leave all settings as they were in part (a) but change the real value of p to .5. Simulate at least 200 tests. Repeat when the real value of p is .6 and .7. Click the button Show Summary. What do you observe about the rejection rate as the true value of p gets further from .4 and closer to 1? Does the pattern that you observe match your impression of how a good test should perform?
