Practice Test 2 Part Ii

Question 1 Answer parts a, b, and c for this research hypothesis The standardized history test scores of high school students who viewed DVDs from the History Channel will be significantly higher than students who listened to their history teachers lectures. State the null hypothesis. The standardized history test scores of high school students who viewed DVDs from the History Channel will not be significantly higher than students who listened to their history teachers lectures. OR There will be no significant difference between standardized history test scores of students viewing DVDs from the History Chanel and those who learned from their teachers lectures. Indicate what statistical test you would use to analyze the data, and explain why you chose that test. Independent t-test We are looking for a difference rather than a correlation, and the two groups of scores are from two different groups of people. There are six possible results listed below. For the statistical test you chose in part b above, explain the results in your own words (circle the results you are explaining). Indicate whether the null hypothesis is accepted or rejected, the reason for acceptance/rejection, and what that means in terms of the real situation described
