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)
