A 9-year-old girl did a science fair experiment in which she tested professional touch therapists to see if they could sense her energy field. She flipped a coin to select either her right hand or her left hand, and then she asked the therapists to identify the selected hand by placing their hand just under her hand without seeing it and without touching it. Among 269269 trials, the touch therapists were correct 107107 times. Use a 0.050.05 significance level to test the claim that touch therapists use a method equivalent to random guesses. Do the results suggest that touch therapists are effective? Identify the null and alternative hypotheses for this test. Choose the correct answer below. A. Upper H 0H0: pequals=0.50.5 Upper H 1H1: pnot equals≠0.50.5 This is the correct answer. B. Upper H 0H0: pequals=0.50.5 Upper H 1H1: pgreater than>0.50.5 C.

Identify the null and alternative hypotheses for this test. Choose the correct answer below.

Upper H 0H0:

pequals=0.50.5

Upper H 1H1:

pnot equals≠0.50.5

This is the correct answer.
