A survey of 58 randomly selected homeowners finds that they spend a mean of $60 per month on home maintenance. Construct a 99% confidence interval for the mean amount of money spent per month on home maintenance by all homeowners. Assume that the population standard deviation is $11 per month. Round to the nearest cent.
