Given below are the number of successes and sample size for a simple random sample from a population. x= 12, n= 40, 98% 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. A. The procedure is appropriate because the necessary conditions are satisfied. ]B. The procedure is not appropriate because n-x is less than 5. C. The procedure is not appropriate because x is less than 5. D. The procedure is not appropriate because the sample is not a simple random sample. c. Select the correct choice below and, if necessary, fill in the answer boxes within your choice. O A. The 98% confidence interval is from (Round to three decimal places as needed. Use ascending order.) to B. The one-proportion z-interval procedure is not appropriate.
