Question

Using Excel (show work)

Suppose a sample of n = 36 freshmen is selected to participate in a new 4-hour training program designed to improve study skills. To evaluate the effectiveness of the new program, the sample was compared with the rest of the freshman class. The mean score on the final exam for the entire freshman class was µ = 74, while scores for the students in the new program are shown below. Based on this data, can we say the training program worked?

Here are the test scores for the 36 students:

79, 56, 45, 100, 74, 74, 83, 82, 97, 75, 89, 87, 51, 99, 42, 85, 95, 88, 100, 58, 73, 98, 59, 65, 74, 85, 100, 87, 98, 56, 99, 45, 100, 80, 100, 79

Also, calculate the appropriate effect size for this test.
