Use the t-distribution to find a confidence interval for a mean given the relevant sample results. Give the best point estimate for μ, 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 90% confidence interval for using the sample results x = 138.0, s = 51.3, and n = 50 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 margin of error = i The 90% confidence interval is i to i
