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 found to be 106.6 with a standard deviation of 13.4. Complete parts (a) through (c) below. Click the icon to view the t-distribution table. Ho=111 to = -2.75 (Round to two decimal places as needed.) Determine the critical value(s) for the H: = versus H: hypothesis test with sample size 70 and = 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 value is B. The critical values are 1.995. For which given values of is the null hypothesis, = , not rejected? (Type whole numbers.) A. B. Ho . or o D.
