A rаndоm sаmple оf nоn-English mаjors at a selected college was used in a study to see if the student retained more from reading a 19th 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 100-point written quiz on each novel. The test results are shown below. All work must be shown for full credit. Student 1 2 3 4 5 6 7 Book 93 81 98 71 79 86 82 DVD 91 74 88 76 73 78 77 a. Why is pairing important in this problem? In other words, why should this research not be done on two different independent samples? b. Find a 98% confidence interval for the mean difference between the Book and DVD scores. c. If a significance test was conducted (α = .02) to determine if the difference is zero, would the null hypotheses be rejected (Please do not actually carry out a significance test)? Support your answer with your findings from part a of this problem. Explain.
