A consumer advocacy group wants to develop a 90% confidence interval for the true mean fuel efficiency. They take a random sample of 64 cars and compute the sample mean to be equal to 35.25. (Assume that the population standard deviation is still 1 mile per gallon.) They ask you to construct the 90% confidence interval. The advocacy group then asks you if there is a 90% chance that the true mean is between the two numbers you just computed. Please compute the 90% Confidence Interval and respond to group's question.
