Since takinga test on a computer is different from taking a test withpencil and paper, one wonders if the scores will bethe same. To investigate this question, researchers createdtwo versions of an SAT-type test and got 20 volunteers toparticipate in an experiment. Each volunteer took bothversions of the test, one with pencil and paper and theother online. Subjects were randomized with respect tothe order in which they sat for the tests (online/paper)and which form they took (Test A, Test B) in whichenvironment. The scores (out of a possible 20) aresummarized in the table.a) Were the two forms (A/B) of the test equivalent interms of difficulty? Test an appropriate hypothesisand state your conclusion.b) Is there evidence that the testing environment (paper/online) matters? Test an appropriate hypothesis andstate your conclusion.
