A professor wants to evaluate whether testing students weekly with a quiz improves their learning of the class material. The professor teaches the same course in two different semesters, with a class size of 30 in both. In the first semester, the students completed a quiz each week. In the second semester, the students were not given any quizzes. Assume that the teaching was otherwise identical in each semester. The course percentage grade for each student is given in the sheet titled Test Scores. a. Analyze whether the class that was given the weekly quizzes scored higher on aver- age in the class. Give a 95% confidence interval as well as an appropriate test result. Be sure to comment on the validity of each of the two methods for this data. b. Analyze whether students were more likely to pass in the class that was given the weekly quizzes. Give a 95% confidence interval as well as an appropriate test result. Be sure to comment on the validity of each of the two methods for this data.
