2. Suppose that, in FEP/UPM, the marks in a business statistics course (MGT 3162) are normally distributed with a mean 68%. To determine the effect of requiring students to pass MTK 3003 (which at present is a prerequisite), a random sample of 25 students who have taken the MTK 3003 given a statistics course. The marks out of 100 are listed below: - (File name: Data2) 784 79 69 64 627 66 88 78 72 75 82 669 60 80 70 62 71 74 69 752 77 61 7779 78 59 59 61 77 90 a. Estimate with 95% confidence the mean statistics mark for all students who have taken MTK 3003. b. Do these data provide evidence at the 5% significance level to infer that students with a statistics (MTK 3003) background would perform better in MGT 3162 than students with no MTK 3003?
