In August 2010, Massachusetts enacted a 150-day right-to-cure period that mandates thatlenders give homeowners who fall behind on their mortgage an extra five months to becomecurrent before beginning foreclosure proceedings. Policymakers claimed that the policy wouldresult in a higher proportion of delinquent borrowers becoming current on their mortgages.To test this claim, researchers took a sample of 244 homeowners in danger of foreclosure inthe time period surrounding the enactment of this law. Of the 100 who fell behind just beforethe law was enacted, 30 were able to avoid foredosure, and of 144 who fell behind just afterthe law was enacted, 48 were able to avoid foreclosure, Let p, and p2 represent the proportionof delinquent borrowers who avoid foredosure just before and just after the right-to-cure lawis enacted, respectively.

An auditor for a local court system is tasked with comparing the rulings of two judges. The auditor needs to determine if Judge Hughes issues shorter sentences than Judge Wilson. The data below are the sentence lengths, in months, issued by each judge in their last twelve cases that dealt with operating a motor vehicle without a license. Test the claim that Judge Hughes issues shorter sentences than Judge Wilson for this particular type of case at the 0.10 level of significance. Let Judge Hughes' sentences be Population 1 and let Judge Wilson's sentences be Population 2. Assume that both populations are approximately normal and that the population variances are equal.

2. Suppose that it was definitively proved that there exists a positive correlation between children playing more violent video games and committing more violent acts in real life. That is, the more hours a child spends playing violent video games, the more likely he is to commit a violent act. Would this prove that violent video games cause children to become more violent? Explain.
One professor who teaches statistics gave students one homework assignment. He asked students to find a two-variable data set and compute the Pearson correlation coefficient. One student found a data set: one variable is students' midterm test score in an introductory microeconomics class and total observations are 45 students; while the other one variable is also students' midterm test score in another introductory microeconomics class and total observations are 57 students. Both of these two classes were taught by the same instructor in spring 2018. Does this student's data set make sense? Why or why not? Discuss and explain your reasons. You must provide your statistical analysis and reasons.

The personality characteristics of business leaders (e.g., CEOS) are related to the operations of the businesses that they lead (Oreg & Berson, 2018). Traits like openness to experience are related to positive financial outcomes and other traits are related to negative financial outcomes for their businesses. Suppose that a board of directors is interested in evaluating the personality of their leadership. Among a sample of n = 16 managers, the sample mean of the openness to experiences dimension of personality was M = 4.50. Assuming that u = 4.24 and o = 1.05 (Cobb-Clark & Schurer, 2012), use a two-tailed hypothesis test with a = .05 to test the hypothesis that this company's business leaders' openness to experience is different from the population.
