A random sample of n = 16 mid-sized cars tested for fuel consumption gave a mean of x = 20.05 miles per gallon with a standard deviation of s= 2.73 miles per gallon. Assuming that the miles per gallon given by aļl mid-sized cars have a normal distribution, find a 99% confidence interval for the population mean, µ. Round your answers to two decimal places.
