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, H, among the general population on this subsection. The website reports that μ is 140, but you have good reason to believe that u differs from 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 134 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? H H:0 0<0 Oso >0 H 0=0 00 (b) Suppose that you decide to reject the null hypothesis.

Question
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, μ, among the general population on this subsection. The website reports that μ is 140, but you have good reason to believe that µ differs from 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 134 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? μ X H:0 OSO >0 H 20 0=0 0#0 (b) Suppose that you decide to reject the null hypothesis.
