- In an early home game, an NBA team made 66 of their 100 free throw attempts. In one of theirlast home games, the team made 68 of 90 attempts. At α = .10, did the team significantlyimprove its free throw percentage (left-tailed test)?A researcher was interested whether an individual's preference in political party affiliation was influenced by their level of education and gender. A random sample of participants were recruited, and preferences were scored from 0 - 10 (0 meaning no preference, 10 meaning greater preference). The researcher then divided participants by gender (1 = male/2 = female) and then again by level of education (1 = some school/2 = college/3 = university). Assume alpha at 0.05.

- Suppose model (XY, XZ, YZ) holds in a 2 x 2 x 2 table, and the common XY conditional log odds ratio at the two levels of Z is positive If the XY and YZ conditional log odds ratios are both positive or both negative, show that the XY marginal odds ratio is larger than the XY conditional odds ratio.For a hypothesis test of the claim that the mean amount of sleep for adults is less than 6 hours, technology output shows that the hypothesis test has power of 0.4733 of supporting the claim that μ<6 hours of sleep when the actual population mean is 4.0 hours of sleep. Interpret this value of the power, then identify the value of β and interpret that value.A car repair company (that receives payments on a daily basis) is going to select which car repair offer toaccept (A, B, C or D) in order to maximize the company incomea) Calculate the expected value (mean) of the different repair offers and indicate which repair offer (A, B, Cor D) to accept (i.e. the one with the maximum expected value).b) If the repair is completed in less than or equal to 3 days, the company will receive an extra one timepayment of 1000 TL in all the offers. Considering this new situation, will the repair that offers the maximumincome change?
