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

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
