Use the t-distribution to find a confidence intervalfor a mean ? given the relevant sample results. Give the best pointestimate for ?, the margin of error, and the confidence interval.Assume the results come from a random sample from a population thatis approximately normally distributed.
A 90% confidence interval for ? using the sample results x=134.0, s= 55.6, and n= 50
Round your answer for the point estimate to one decimal place,and your answers for the margin of error and the confidenceinterval to two decimal places.
point estimate =
margin of error =
the 90% confidence interval =
