One personality test available on the World Wide Web has a subsection designed to assess the "honesty" of the test-taker. After taking the test and seeing yourscore for this subsection, you're interested in the mean score, µ, among the general population on this subsection. The website reports that µ is 142, but youbelieve that u is less than 142. You decide to do a statistical test. You choose a random sample of people and have them take the personality test. You find thattheir mean score on the subsection is 135 and that the standard deviation of their scores is 28.Based on this information, answer the questions below.What are the null hypothesis (H) and the alternative hypothesis (H,) that should be used for the test?Ho: u is ??|H,: µ is ?H :?In the context of this test, what is a Type II error?A Type II error is ?v the hypothesis that u is ?v when, infact, μ is| ??Suppose that you decide not to reject the null hypothesis.
