Question
Use the t-distribution to find a confidence interval for a mean u given the relevant sample results. Give the best point estimate for u,
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 u using the sample results I = 13.3, s = 4.9, 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 =
13.3

margin of error =
i
The 95% confidence interval is
