Unformatted text preview: Shuffle the cards. Perform the following experiment for all 30 cards: Ask the subject if the first card in the stack is red or black. Then ask them if the second card is red or black, and so on, until they have made guesses for all 30 cards. Record whether or not each response is correct or incorrect. Suppose that a person has ESP if they get significantly more than 50% of the responses correct. Test the claim that the proportion of correct responses is greater than 50%. Use α = 0.05. n = _30_ x = ______ I. H : H 1 : II. α = 0.05 Critical Value = III. Test Statistic = (round to 2 decimals) IV. (picture) V. P-value = (round to 4 decimals) VI. Reject H or Do Not Reject H VII. (conclusion) Based on the results of this hypothesis test, does your subject have ESP? Yes or No...
