A 90% confidence interval for using the sample results x = 137.0, s = 53.9, and

A 90% confidence interval for μ using the sample results x̅ = 137.0, s = 53.9, and n = 50

Use the t-distribution to find a confidence interval for a mean μ 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.
