At many golf clubs, a teaching professional provides a free 10-minute lesson to new customers. A golf magazine reports that golf facilities that provide these free lessons gain, on average, $1,600 in green fees, lessons, or equipment expenditures. A teaching professional believes that the average gain exceeds $1,600. Complete parts a through c below. a. In order to support the claim made by the teaching professional, what null and alternative hypotheses should you test? Ho: $1,600 V$1,600 b. Suppose you select a = 0.05. Interpret this value in the words of the problem. The probablility that the null hypothesis is V when the average gain $1,600 is 0.05. c. For a = 0.05, specify the rejection region of a large-sample test. Choose the correct answer below. O A. z< -2.33 O B. - 1.6451.645 O D. z< -1.645 O E. - 1.96 1.645 O G. z< -1.96 or z> 1.96 O H. z>2.33

A researcher designs an intervention to combat anti-Arab oppression. She also designs a questionnaire to measure anti-Arab oppression so she can test the participants' level of anti-Arab oppression before and after the intervention. She tests one version of her questionnaire with 45 statements and a shorter version with 12 statements. In both questionnaires, the participants respond to each statement with a rating on a 5-point Likert scale with 0 equaling "strongly disagree" and 4 equaling "strongly agree." The overall score for each participant is the mean of his or her ratings for the different statements on the questionnaire. Look at the following graphs. Graph I graphs the results from the long version, and Graph II graphs the results from the short version.
