Arandom sample of n = 16mid - siz sized cars tested for fuel consumption gave a mean of overline x =24.84 miles per gallon with a standard deviation of s = 2.22 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
