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 fipped 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 257 trials, the touch therapists were correct 105 times Use a 0.01 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? dentify the null and alternative hypotheses for this test. Choose the correct answer below. OB. Ho pa05 H pc05 OD. H, pr05 H,: p-05 OA. Ho pa05 H, p>05 C. Họ p=05 H, pr05 Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test is o two decimal places as needed.) (Round t Identify the P-value for this hypothesis test. The P-value for this hypothesis test is (Round to three decimal places as needed.) Identify the conclusion for this hypothesis test. OA. Reject Ho. There is not sufficient evidence to warrant rejection of the claim that touch therapists use a method equivalent to random guesses. O B. Fail to reject Ho. There is sufficient evidence to warrant rejection of the claim that touch therapists use a method equivalent to random guesses. OC. Fail to reject Ho. There is not sufficient evidence to warrant rejection of the claim that touch therapists use a method equivalent to random guesses. OD. Reject Ho. There is sufficient evidence to warrant rejection of the claim that touch therapists use a method equivalent to random guesses. Do the results suggest that touch therapists are effective? The results suggest that the touch therapists performed random guesses, so they to be effective.
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
