The number of successes and the sample size for a simple random sample from a population are given below. x: 9, n = 36, H0: p =04, Ha: p0.4, (1:0.01 a. Determine the sample proportion. b. Decide whether using the one-proportion z-test is appropriate. (2. If appropriate. use the one-proportion z-test to perform the specied hypothesis test. Click here to view a table of areas under the standard normal curve for negative values of z. Click here to view a table of areas under the standard normal curve for positive values of z. 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? {:3 No C) Yes c. Determine the test statistic, if appropriate. Select the correct choice below and, if necessary, till in the answer box to complete your answer. \":3 A- z = (Round to two decimal places as needed.) {:3 B. The one-proportion ztest is not appropriate. Identify the critical value(s), if appropriate. Select the correct choice below and, if necessary, ll in the answer box to complete your answer. [:3 A- za = (Round to two decimal places as needed.) U 3- 2a = {Round to two decimal places as needed.) [:3 3- izai'Z i (Round to two decimal places as needed.) [:3 D. The one-proportion z-test is not appropriate. What is the conclusion of the hypothesis test? O A. Do not reject Ho; the data do provide sufficient evidence to conclude that p # 0.4. O B. Reject Ho; the data do not provide sufficient evidence to conclude that p # 0.4. O C. Reject Ho; the data do provide sufficient evidence to conclude that p # 0.4. O D. Do not reject Ho; the data do not provide sufficient evidence to conclude that p # 0.4. O E. The one-proportion z-test is not appropriate.Given below are the number of successes and sample size for a simple random sample from a population. x = 17, n =20, 95% level a. Determine the sample proportion. b. Decide whether using the one-proportion z-interval procedure is appropriate. c. If appropriate, use the one-proportion z-interval procedure to find the confidence interval at the specified confidence level. d. If appropriate, find the margin of error for the estimate of p and express the confidence interval in terms of the sample proportion and the margin of error.a. p = (Type an integer or a decimal. Do not round.) b. Is the one-proportion z-interval procedure appropriate? Select all that apply. 3 A. The procedure is not appropriate because the sample is not a simple random sample. 3 B. The procedure is not appropriate because x is less than 5. :1 C. The procedure is appropriate because the necessary conditions are satised. 3 D. The procedure is not appropriate because n - x is less than 5. c. Select the correct choice below and, if necessary, fill in the answer boxes within your choice. O A. The 95% confidence interval is from to (Round to three decimal places as needed. Use ascending order.) O B. The one-proportion z-interval procedure is not appropriate. d. Select the correct choice below and, if necessary, fill in the answer boxes within your choice. O A. The margin of error is The 95% confidence interval is (Type integers or decimals. Round to three decimal places as needed.) O B. The one-proportion z-interval procedure is not appropriate.The number of successes and the sample size for a simple random sample from a population are given below. x =6, n=24. H0: p= 0.4, Ha: p
