Please help with #15 Suppose population 1 consists of all students who picked up all the tests they completed prior totaking the final exam. Suppose population 2 consists of all students who had one or more teststhat 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 thatthe mean final exam grade for all students who picked up all their tests is greater than the mean final examgrade 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, andthe mean score on final exam for this sample of students was 83 with a standard deviation of10.4. An independent simple random sample of 51 students who had one or more tests thatwere not picked up was selected, and the mean score on the final exam for this sample ofstudents was 67 with a standard deviation of 24.2. Both distributions are skewed heavily tothe left.
