Therapeutic touch (TT) practitioners claim to perceive an energy field above a patient's skin. To test this claim a TT practitioner was blind-folded and the researcher placed her hand over either the right or left hand of the practitioner. Let p denote the probability of a correct prediction by a TT practitioner. An experiment used 10 TT practitioners who had to predict the correct hand in each of 12 trials. Complete parts a through e. CCIDE a. Define the parameter of interest and set up hypotheses to test that the probability of a correct guess is 0.50 against the TT practitioners' claim that it exceeds 0.50. Define a parameter of interest. Choose the correct answer below. OA. H=average number of correct guesses B. p=probability of a correct guess O c. a standard deviation of correct guesses Set up the hypotheses for the hypothesis test. Ho: P = 0.5 H₂: P > 0.5 (Type integers or decimals. Do not round.) b. The 120 trials had 66 correct guesses. Find and interpret the test statistic. Select the correct choice below and fill in the answer box to complete your choice. (Round to two decimal places as needed.) A. The test statistic is z= OB. The test statistic is z = which represents the difference between the sample estimate and the null hypothesis value. which represents the number of standard errors that the estimate falls from the null hypothesis value.

Transcribed Image Text:Therapeutic touch (TT) practitioners claim to perceive an energy field above a patient's skin. To test this claim a TT practitioner was blind-folded and the researcher placed her hand over either the
right or left hand of the practitioner. Let p denote the probability of a correct prediction by a TT practitioner. An experiment used 10 TT practitioners who had to predict the correct hand in each of 12
trials. Complete parts a through e.
a. Define the parameter of interest and set up hypotheses to test that the probability of a correct guess is 0.50 against the TT practitioners' claim that it exceeds 0.50.
Define a parameter of interest. Choose the correct answer below.
OA. μ=average number of correct guesses
B. p=probability of a correct guess
O c. o=standard deviation of correct guesses
Set up the hypotheses for the hypothesis test.
Ho: P
0.5
Ha: p
0.5
(Type integers or decimals. Do not round.)
b. The 120 trials had 66 correct guesses. Find and interpret the test statistic.
Select the correct choice below and fill in the answer box to complete your choice.
