- Chris (that’s me) wanted to know if Exam 3 was a lot harder
than Exam 1 in his statistics class. In order to answer his
research question, he looked at the Exam 1 grades of N =
30 students and then looked at the same students’ Exam 3 grades. He
found that the average score for Exam 1 was M1
= 88.67, Exam 3 was M2 = 80.60, and that the
standard deviation of the difference was sD =
10.1 Use α = .05 and one-tailed test,
what is the obtained t-statistic?
- -1.699
- -4.000
- -0.790
- -2.530
