The average GPA of students enrolled in an AP Statistics class is higher than 3.5. (2 points) b.) The average retirement age of professional bull riders is less than 30 years. (2 points) c.)

9. (14 points) For each scenario below, indicate the appropriate test and alternative hypothesis by selecting two let- ters from the following: (A) single mean, (B) difference of means, (C) paired means, (D) correlation, (E) single proportion, (F) difference of proportions. (G) chi-square independence, (X)H: < or H : > Bo, (Y) H :8 , and (Z) H, the 2 nominal variables are not independent.

Test the given claim. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, and then state the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim. Among 2031 passenger cars in a particular region, 227 had only rear license plates. Among 300 commercial trucks, 45 had only rear license plates. A reasonable hypothesis is that commercial trucks owners violate laws requiring front license plates at a higher rate than owners of passenger cars....

1. A hypothesis has been proposed that breast cancer in women is caused in part by events that occur between the age of menarche (time of 1st menstruation) and the age of first childbirth. The hypothesis is that the risk for breast cancer increases as the length of this time interval increases. To test this hypothesis an international study was set up. Breast cancer cases were identified among women in selected hospitals in the United States, Greece, Yugoslavia, Brazil, Taiwan...
