A random sample of n = 16 mid-sized cars tested for fuel consumption gave a mean of x = 20.55 miles per gallon with a standard deviation of s = 3.00 miles per gallon. Assuming that the miles per gallon given by all mid-sized cars have a normal distribution, find a 99% confidence interval for the population mean, u. Round your answers to two decimal places.
