    Question

    A psychologist is researching the effect of hypnosis on brain dominance. He does an experiment with 6 students. On the first day, they are hypnotized. Then they take a test that shows how dominant the right hemisphere is relative to the left hemisphere (the higher the score, the more dominant the right side). On another day, the same test is taken, but the students are not hypnotized. The data collected are below:

    The psychologist knows that the scores are not normally distributed and wants to apply a nonparametric test to see if hypnosis makes dominance significantly higher. What is the result of the test at α=.05\alpha = .05?


    1. TRUE: We should H0H_0 reject because TT is smaller than Tcrit=2T_{crit} = 2.
    2. FALSE: We can H0H_0 do not reject because TT is greater than Tcriticality=0T_{criticality} = 0.
    3. FALSE: We can H0H_0 do not reject because TT is smaller than Tcriticality=2T_{criticality} = 2.
    4. FALSE: We must H0H_0 reject because TT is greater than Tkritiek=0T_{kritiek} = 0.
