![One personality test available on the World Wide Web has a subsection designed to assess the "honesty" of the test-taker. You are interested in the mean score,
u, among the general population on this subsection. The website reports that μ is 140, but you have good reason to believe that u is greater than 140. You
decide to do a statistical test. You choose a random sample of people and have them take the personality test. You find that their mean score on the subsection
is 147 and that the standard deviation of their scores is 28.
Based on this information, complete the parts below.
(a) What are the null hypothesis Ho and the alternative hypothesis H, that should be used for the test?

Ho
H₁:0
(b) Suppose that you decide to reject the null hypothesis. What sort of error might you be making?
(Choose one) ▼
(c) Suppose the true mean score among the general population on the subsection is 150. Fill in the blanks to describe a
Type II error.
A Type II error would be (Choose one) the hypothesis that u is (Choose one)
(Choose one) when, in fact, u is (Choose one)
