A simple random sample of men is obtained and theelbow-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=13.7, s=0.6. Determine the critical value of t and the margin oferror, and then construct the95% confidence interval estimate for the population mean.

The critical value is t=
