a. Let p denote the population proportion of correct hand selections by touch therapists. Identify the null and alternative hypotheses to test the claim that touch therapists use a method equivalent to random guesses. b. Identify the test statistic. c. Identify the P-value. d. State the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim. Address whether the results suggest that touch therapists are effective.

Transcribed Image Text:When she was 9 years of age, a 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 242 trials,
the touch therapists were correct 103 times. Use a 0.10 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?
Let p denote the population proportion of correct hand selections by touch therapists. Identify the null and alternative hypotheses to test the claim that touch therapists use a method equivalent to
random guesses.
