Students at a high school are asked to evaluate their experience in the class at the end of each school year. The courses are evaluated on a 1-4 scale ā€“ with 4 being the best experience possible. In the History Department, the courses typically are evaluated at 10% 1ā€™s, 15% 2ā€™s, 34% 3ā€™s, and 41% 4ā€™s. Mr. Goodman sets a goal to outscore these numbers. At the end of the year he takes a random sample of his evaluations and finds 10 1ā€™s, 13 2ā€™s, 48 3ā€™s, and 52 4ā€™s. At the 0.05 level of significance, can Mr. Goodman claim that his evaluations are significantly different than the History Departments
