Inferential Statistics Section 20. Bob draws a simple random sample from an extremely large population of lemons. The sample size is n = 570 and in the sample 310 lemons turn out to be good and 260 lemons turn out to be bad. Find the 99% confidence interval for the population proportion p of good lemons. A.
