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=31​, x=14.1​, s=0.7. 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 is t =?
