Use the t-distribution to find a confidence interval for a mean given the relevant sample results. Give the best point estimate for u. 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 = 82.3, s = 32.3, 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. point estimate i 82 margin of error= 2.58 The 99% confidence interval is 60.82 to 103.78
