Target Topic: Improve scores in Mathematics examination for students who participated in Special Program compared to those students who do not. Target Method: Pool Variance T-Test A random sample of scores obtained in a mathematics examination by 9 students who participated in the special program and eight students who did not take the special program. Below are the scores of the students: 90 91 89 88 90 93 94 95 89 Participated Did not participate 90 88 87 88 86 90 93 88 Test whether the average scores of those who participated is higher than the average scores who did not participate at the 5% level of significance. Assume that the mathematics examination scores of the students are normally distributed with unknown but equal variances.
