Use the t-distribution to find a confidence interval for a mean given the relevant sample results. Give the best point estimate for , the margin of error, and the confidence interval. Assume the results come from a random sample from a population that is approximately normally distributed.

A 99% confidence interval for using the sample results x-bar = 93.8, s = 30.4, and n=15

Round your answer for the point estimate to one decimal place, and your answers for the margin of error and the confidence interval to two decimal places
