Skillbuilder Applet Exercise estimates the pvalue for a one-tailed hypothesis test by simulating the taking of many samples.

The given hypothesis test is for an Ho: 1500 versus Ha: 1500. A

Population: Ben 1500 0.04 0.02 1450 1400 1500 1520 Sple 1440 1400

sample of 24 has been taken and the sample mean is 1451.

a. Click “10” for “# of samples.” Note the sample means and the probability of being less than 1451 if the true mean is really 1500.

b. Change to “Batch” and simulate 1000 more samples. What is the probability of being less than 1451? This is your estimated p-value.

c. How does your estimated p-value show on the histogram formed from the taking of many samples? Explain what this p-value means with respect to the test.

d. If the level of significance were 0.01, what would your decision be?
