Homework Help: Statistics help?

Posted by Evan on Monday, November 26, 2012 at 5:34pm.

Hi there, I was looking for any assistance or help on how I would go about starting this assignment? Having difficulty understanding it. Thank you in advance.

"A stats instructor is interested in investigating time of day his lectures were held on student' test scores. He selected a sample of 15 students from his morning (n=7) and evening (n=8) statistics classes and recorded their midterm and final exam scores (shown below). He was interested in examining whether students performed better in morning vs. evening classes on their final exam scores. He also suspected poorer performance on the final exam compared to the midterm among those attending the morning class.

Morning Class (n=7):
Midterm | Final
80 | 59
80 | 64
75 | 65
92 | 70
78 | 67
79 | 58
69 | 79

Evening Class (n=8):
Midterm | Final
62 | 40
70 | 45
80 | 55
78 | 55
84 | 60
64 | 70
84 | 60
64 | 70
84 | 60
64 | 70
84 | 60
70 | 63

The instructor was also curious about what type of exam students preferred to receive in the course (multiple choice or short-answer). He observed the morning class, 6 students preferred multiple choice exams. Evening class, 2 students preferred multiple choice. Does he have evidence that 50% of the students preferred multiple choice exams in the evening class? Finally, can the instructor conclude that there is a relation between test type preference and time of class? If yes, please measure the strength of the relation."
