A teacher wants to determine whether a note taking technique improves students test results. Each student completes a pretest before learning the technique and a posttest after applying the note taking technique. The teacher claims the posttest scores will be at least the scores on the pretest.
Based on the data in the table and using a significance level of 0.05, find the p-value and the conclusion of the test.
Responses
p-value = 0.9975; Reject
p-value = 0.0025; Fail to reject
p-value = 0.9975; Fail to reject
p-value = 0.0025; Reject
Table:
student: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10,
Pretest: 90, 82, 70, 81, 75, 74, 78, 89, 83, 79
Posttest: 96, 85, 72, 82, 80, 77, 78, 92, 89, 78
Difference: 6, 3, 2, 1, 5 ,3, 0, 3, 6, -1
