A random sample of n = 16 mid-sized cars tested for fuel consumption gave a mean of x̄ = 20.56 miles per gallon with a standard deviation of s = 2.38 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, μ. Round your answers to two decimal places.

A random sample of n=16 mid-sized cars tested for fuel consumption gave a mean of x̄=21.58 miles per gallon with a standard deviation of s=2.55 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, μ. Round your answers to two decimal places.
