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:H0: μd=0μd=0
H1:H1: μdμd >> 00
What is the test statistic?
test statistic = Incorrect (Report answer accurate to 3
decimal places.)
What is the p-value for this sample?
p-value = Incorrect (Report answer accurate to 3 decimal
places.)
