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 Method New Method 76.4 69.6 66.0 81.1 66.6 77.2 89.9 85.4 66.3 67.9 77.5 70.3 63.2 33.4 55.6 42.0 13.8 10.7 36.9 71.6 37.9 23.7 14.5 26.6 55.2 Some Summary Statistics are given below: Er Ex?
