Two random samples of 40 students were drawn independently from two populations of students. Assume their aptitude tests are normally distributed and assume the variances of each sample are equal. The following statistics regarding their scores in an aptitude test were obtained: x with bar on top subscript 1 equals 76 comma space s subscript 1 equals 8 comma space x with bar on top subscript 2 equals 71 comma space s subscript 2 equals 7.5. Test at the 5% significance level to determine whether we can infer that the two population means differ. What is the conclusion from your test
