The confidence interval at 95% confidence level for estimating the population proportion if the sample size is 500 and the number of successes in the sample is 221 is (0.404, 0.488).
Added by Noelia G.
Step 1
We are given the sample size (n) as 500 and the number of successes (X) as 221. We are also given the confidence level, which is 95%. Show more…
