Use the t-distribution to find a confidence interval for a mean 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 using the sample results = 87.9, s = 7.0, and n = 42 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 = i margin of error = The 95% confidence interval is i to i

Transcribed Image Text:Use the t-distribution to find a confidence interval for a mean u given the relevant sample results. Give the best point estimate for µ,
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 = 87.9, s = 7.0, and n 42
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.
