hello plz fast just answers no explanation
A sample of non-English majors at a selected college was used in
a study to see if the student retained more from reading a 19 th-
century novel or by watching it in DVD form. Each student was
assigned one novel to read and a different one to watch , and then
they were given a 20-point written quiz on each novel. Assume the
variables are normally distributed . The test results are
shown below.
Book 88 73
91 85
93 95
90 90 80
90
DVD 80 95
95 92
93 80
92 75
70 80
At α = 0.10, can it be concluded that the book scores are
higher than the DVD scores? (Consider the difference D= Before -
After)
a) State the hypotheses and identify the claim with the correct
hypothesis.
1.
H0:µD =0 Not
claim
H1:µD ≠0 claim
2.
H0:µD≥ 0 Not
claim
H1:µD <0
claim
3.
H0:µD ≤0 Not
claim
H1:µD >0
claim
b) Find the critical value (s).
1. CV=1.383
2. CV= 1.833
3. CV= -2.262
c) Compute the test value:
1.t= 0.235
2. t=0.626
3. t= 0.988
d) Make the decision.
1. Reject the null hypothesis.
2.Do not reject the null hypothesis.
e) Summarize the results.
1. There is enough evidence to support the claim.
2.There is not enough evidence to support the claim.
