teacher would like to determine if quiz scores improve after completion of a worksheet. The students take a pre-quiz before the worksheet and then another quiz after the worksheet. Assume that the quiz scores are normally distributed. The grades for each quiz are given below. Use a significance level of α = 0.05 . List 1 has the post-quiz scores. List 2 has the pre-quiz scores. The hypothesis test is to see if the Post-Quiz Scores are > the Pre-Quiz Scores So, H 0 : μ d = 0 H 1 : μ d > 0 post-quiz pre-quiz 11 13 7 13 17 14 18 17 13 13 6 6 16 12 21 18 14 7 18 14 What is the test statistic? test statistic = (Report answer accurate to 3 decimal places.) What is the p-value for this sample? p-value = (Report answer accurate to 3 decimal places.) The correct decision is to . The correct summary would be: that the worksheet did improve the average quiz scores

List 1 has the post-quiz scores.
List 2 has the pre-quiz scores.
The hypothesis test is to see if the Post-Quiz Scores are > the Pre-Quiz Scores
