Question

A friend of yours claims to be psychic. You are skeptical. To test this you take a stack of 100 playing cards and have your friend try to identify the suit (hearts diamonds, clubs, or spades), without looking, of course! If you were to do a hypothesis test on this experiment, would your alternative hypothesis be one-sided or two-sided? Explain why. Choose the correct answer below. A. The alternative hypothesis would be two-sided because the only evidence that would support your friend's claim is guessing more or less than 1/4 of the suits correctly. B. The alternative hypothesis would be one-sided because the only evidence that would support your friend's claim is guessing more than 1/14 of the suits correctly. C. The alternative hypothesis would be two-sided because the only evidence that would support your friend's claim is guessing less than 1/4 of the suits correctly. D. The alternative hypothesis would be one-sided because the only evidence that would support your friend's claim is guessing less than 1/4 of the suits correctly.
