A random sample of 63 trucks were tested for highway fuel economy and the sample had a mean of 27.1 miles per gallon with a standard deviation of 1.3 miles per gallon.Using a 95% confidence level, determine the margin of error,E, and a confidence interval for the average highway fuel economy of this new truck. Report the confidence interval using interval notation.
