- researcher wishes to estimate the proportion of adults who have high-speed Internet access. What size zample should be obtained if she wishes the estimate to be within 0.03 with 99% confidence. Assume there was a small pilot study where the proportion was estimated at 52. (Show Work) A simple random sample of size n is drawn from a population that is normally distributed. The sample mean is found to be 111, and the sample standard deviation is found to be 10. If the sample size was 50, what is the 95% confidence interval? (Show Work) Would the 99% confidence interval be wider or narrower?
