Suppose population 1 consists of all students who picked up all the tests they completed prior taking the final exam. Suppose population 2 consists of all students who had one or more tes that they completed that were not picked up prior to taking the final exam. Based on years of grading final exams and observing grades, STAT 210 instructors conjecture that the mean final exam grade for all students who picked up all their tests is greater than the mean final exam grade for all students who had one or more tests that were not picked up. A simple random sample of 56 students who picked up all tests they completed was selected, ar the mean score on final exam for this sample of students was 83 with a standard deviation 10.4. An independent simple random sample of 51 students who had one or more tests th
