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=38, x over bar=14.2, s=0.9 Determine the critical value of t and the margin of error, and then construct the 95% confidence interval estimate for the population mean. The critical value of t is? (round to three decimal places). What is the margin of error? (round to three decimal places). Find the 95% confidence interval ?< mean (round to one decimal place)
