Use the t-distribution to find a confidence interval for a mean μ given the relevant sample results
Chapter 6, Section 2-CI, Exercise 084
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.
