The number of days marathon runners practice before an event are normally distributed with an unknown population mean and standard deviation. If a random sample of 28 runners is taken and results in a sample mean of 16 days and sample deviation of 2 days, find a 99% confidence interval estimate for the population mean using the Student's t-distribution.   df t0.10 t0.05 t0.025 t0.01 t0.005 ... ... ... ... ... ... 25 1.316 1.708 2.060 2.485 2.787 26 1.315 1.706 2.056 2.479 2.779 27 1.314 1.703 2.052 2.473 2.771 28 1.313 1.701 2.048 2.467 2.763 Provide your answer below:
