A random sample of n=16 mid-sized cars tested for fuel consumption gave a mean of x̄=22.85 miles per gallon with a standard deviation of s=2.62 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.
