Question
find test statistic AND p value
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 275 trials, the touch therapists were correct 121 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.
