A 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=0.05α=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, H0: μd=0 H1: μd >> 00 post-quiz pre-quiz 10 9 13 8 16 16 17 15 10 7 14 19 14 12 14 13 14 14 11 9 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
A 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=0.05α=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,
H0: μd=0
H1: μd >> 00
post-quiz | pre-quiz |
---|---|
10 | 9 |
13 | 8 |
16 | 16 |
17 | 15 |
10 | 7 |
14 | 19 |
14 | 12 |
14 | 13 |
14 | 14 |
11 | 9 |
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
