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 95% confidence interval for / using the sample results x = 14.9, s = 5.0, and n = 30 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 = HI The 95% confidence interval is i to HI
