A random sample of n=16 mid-sized cars tested for
fuel consumption gave a mean of x¯=29.87 miles per
gallon with a standard deviation of s=2.27 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.
