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. A 90% confidence interval for µ using the sample results x̄ =2.9 s=0.2, and n=100. WHAT IS THE SAMPLE STATISTIC? MARGIN OF ERROR? CONFIDENCE INTERVAL OF 90%
