THANK YOU In a European university, we want to test the hypothesis that the intelligence quotient (IQ) of the students who study physics and mathematics is different from the average IQ of the entire university, for which a sample of 30 students from these two careers is taken. If the average IQ of the entire university is 118, construct two decision rules that allow this hypothesis to be tested, a) Considering values of alpha = 0.01 b) Considering values of alpha=0.40 Suppose that the results obtained in the sample are the following and have a normal distribution: 147.5, 144.7, 149.2, 144.5, 143.6, 139.6, 151.6, 140.6, 151.1, 139.2, 140.8, 156.9, 158.0, 145.3, 146.1, 148.5, 145.0, 143.2, 141.4, 149.6, 152.2, 145.6, 149.4, 151.3, 150.0, 151.5, 146.2, 147.7, 148.9, 146.6
A case-control study is being planned to see whether proximity to a nuclear power plant is associated with the development of certain cancers. 200 cases and 200 controls will be recruited and the distance from the nearest nuclear power plant will be dichotomized as close (< 3 miles) or far (≥ 3 miles). Use SAS to complete each problem below. (d) Since investigators find it very difficult to recruit cases, they decide to recruit three times as many controls as cases. How many cases and controls will they need to recruit in order to have 80% power? (Still assume a 2-sided, 5% level test, the same exposure probability among controls, and same OR.) If everything stays the same as above but the level of the test is reduced below 5%, what would happen to the total sample size computed first? (e) It is believed that about 4% of controls live close to the plant and the OR that investigators would be interested in detecting is 3.5. Assuming that a 2-sided, 5% level test will be…
