intro stats, trucker confidence interval

How do I solve this problem?

According to a study of 90 truckers, a trucker drives, on average, 540 miles per day. If the standard deviation of the miles driven per day for the population of truckers is 40, find the 99% confidence interval of the mean number of miles driven per day by all truckers?

Re: intro stats, trucker confidence interval

You really should have all the equations you need in your book to solve this. Have you at least made some attempt at it? Or specific what about it you don't understand.
