A simple random sample of thirty-six students has a mean age equal to x = 28.50 years, determine a 95% confidence interval estimate for u given o = 6.24 years. Give your answers to two decimal places. Determine the sample size needed for a maximum margin of error of two years for the 95% confidence interval estimate for u given a = 6.24
