A random sample of \( n = 16 \) mid-sized cars tested for fuel consumption gave a mean of \( \bar{x} = 25.04 \) miles per gallon with a standard deviation of \( s = 2.47 \) 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, \( \mu \).

Round your answers to two decimal places.

\[ \square \quad \leq \, \mu \, \leq \quad \square \]
