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 x̄ = 79.7, s = 6.6, and n = 42

Round the 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 _________
