PROBLEM 1. The researcher conducted an experiment to determine whether sleep duration has an effect on the level of concentration of college students. Participants in one group were asked to sleep for four hours while the participants in another group was asked to sleep for eight hours. They were asked to complete a buzz wire test to determine their level of concentration. The shorter time the participants completed the test, the higher their concentration level is. He wanted to test the hypothesis at 0.05 level of significance. The following results were gathered:
