A simple random sample of men is obtained and the elbow-to-fingertip length of each man is measured. The population of those lengths has a distribution that is normal. The sample statistics are n = 36, x= 13.8, s = 0.6. Determine the critical value of t and the margin of error, and then construct the 95% confidence interval estimat the population mean. The critical value is t=. (Round to three decimal places as needed.) The margin of error is (Round to three decimal places as needed.) Find the 95% confidence interval. (Round to one decimal place as needed.)
