3. The number of successes and the sample size for a simple random sample from a population are given below. x = 40, n=50, Ho: p=0.7, Ha:p>0.7, a=0.10 a. Determine the sample proportion. b. Decide whether using the one-proportion z-test is appropriate. c. If appropriate, use the one-proportion Z-test to perform the specified hypothesis test. a. The sample proportion is (Type an integer or a decimal. Do not round.) b. Is it appropriate to use the one-proportion z-test? (1) appropriate, because the sample (2) a simple random sample and (3) c. Determine the test statistic, if appropriate. Select the correct choice below and, if necessary, fill in the answer box to complete your answer. OA. Z= (Round to two decimal places as needed.) OB. The one-proportion z-test is not appropriate. Identify the P-value, if appropriate. Select the correct choice below and, if necessary, fill in the answer box to complete answer. A. The P-value is (Round to three decimal places as needed.) B. The one-proportion z-test is not appropriate. What is the conclusion of the hypothesis test? A. Do not reject Hoi the data do not provide sufficient evidence to conclude that p>0.7. OB. Reject Ho; the data do not provide sufficient evidence to conclude that p>0.7. OC. Do not reject Hoi the data do provide sufficient evidence to conclude that p>0.7. OD. Reject Ho; the data do provide sufficient evidence to conclude that p>0.7. O E. The one-proportion z-test is not appropriate. (1) O Yes, it is (2) is not are less than 5. O No, it is not is (3) O both npo and n(1-P) про is 5 or greater but n (1-Po) is less than 5. both np, and n (1-P) are 5 or greater Onpo is less than 5 but n (1-P) is 5 or greater. In -P
