found to be 107.5 with a standard deviation of 12.2. Complete parts (a) through (c) below. Suppose you wish to determine if the mean IQ of students on a certain campus is different from the mean IQ in the general population, 100. To conduct this study, you obtain a simple random sample of 70 students on this campus, administer an IQ test, and record the results. The mean IQ of the sample of 70 students is (a) Construct a hypothesis test Ho: U= Ho versus H, : H # Ho for Ho = 103, 104, 105, 106, 107, 108, 109, 110, 111, and 112 at a= 0.05 level of significance. Determine the test statistics for Ho = 103, 104, 105, 106, and 107. Ho = 103 to = 3.09 Ho = 104 to = 2.4 Ho = 105 to = 1.71 Ho = 106 to = 1.03 Ho = 107 to = .34 Round to two decimal places as needed.) Determine the test statistics for Ho = 108, 109, 110, 111, and 112. Ho = 108 to = -.34 Ho = 109 to = - 1.03 Ho = 110 to = - 1.71 Ho = 111 to = - 2.4 Ho = 112 to = - 3.09 (Round to two decimal places as needed.) Determine the critical value(s) for the Ho: =Ho versus H,: H #Ho hypothesis test with sample size 70 and a= 0.05 level of significance. Select the correct choice below and fill in the answer box(es) within your choice. (Round to three decimal places as needed.) A. The critical values are + 1.995 B. The critical value is For which given values of Ho is the null hypothesis, H = Ho, not rejected? (Type whole numbers. O A. HOS O B. SHOS O C. Hos or Ho OD. Ho 2
