Question 12 of 30 - 14 View Policies Current Attempt in Progress Use the t-distribution to find a confidence interval for a mean / given the relevant sample results. Give the best point estimate for M, 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 u using the sample results x = 89.7, s = 30.7, 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 = margin of error = i The 99% confidence interval is i to
