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 99% confidence interval for μ using the sample results x¯=48.6, s=10.8, and n=10Round 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 = The 99% confidence interval is

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 95% confidence interval for μ using the sample results x¯=11.0, s=4.6, 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 = The 95% confidence interval is to .
