Use the t-distribution to find a confidence interval for a mean μμ given the relevant sample results. Give the best point estimate for μμ, 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 μμ using the sample results x⎯⎯=145.2x¯=145.2, s=53.7s=53.7, and n=50n=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 = Enter your answer; point estimate margin of error = Enter your answer; margin of error The 90% confidence interval is Enter your answer; The 90%confidence interval, value 1 to Enter your answer; The 90%confidence interval, value 2 .
