Given below are the number of successes and sample size for a simple random sample from a population. x 46, n 50, 99% 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
