Question
I. In the following study educational researchers were interested in whether a New
Method for teaching mathematics was more effective than the Standard Method. A
sample of 20 students were taught by the Standard Method, while another sample of
15 students were taught by the New Method. Each student was given a mathematics
proficiency test at the end of the teaching period. The scores on this test are tabulated
below:
Standard 54.2 61.9 69.2 76.1 55.8 67.3 73.9 67.3 73.9 71.4
