34 A psychоlоgist is studying the effects оf dreаm deprivаtion on а person's anxiety level during waking hours. Brain waves, heart rates, and eye movements can be used to determine if a sleeping person is about to enter into a dream period. Three groups of subjects were randomly chosen from a large group of college students who volunteered to participate in the study. Group 1 subjects had their sleep interrupted four times each night, but never during or immediately before a dream. Group 2 subjects had their sleep interrupted four times also, but on two occasions they were awakened at the onset of a dream. Group 3 subjects were wakened four times, each time at the onset of a dream. This procedure was repeated for 10 nights, and each day all subjects were given a test to determine their levels of anxiety. The table shows the total of the test scores for each subject over the entire project. Higher totals mean higher levels of anxiety. Test the claim that the mean anxiety score is the same in all three groups. State the null and alternative hypotheses. Group 1 Group 2 Group 3 9 10 15 7 9 11 3 11 12 6 10 9 5 7 10 8 6 8
