A researcher is interested in whether doing practice problems helps students to increase their grade on their statistics test. He gets a sample of n =16 students in a statistics class and gives them a test before they do any practice problems. The average score on Test 1 is M1 = 74.83. He then makes them do practice problems and gives the same sample of students another test. The average score on Test 2 is M2 = 82.67. The SS of the difference is 400. What type of statistical test should be used to answer this research question?
