A corporation monitors time spent by office workers browsing the web on their computers instead of working. In a sample of computer records of 31 workers, the average amount of time spent
browsing in an eight-hour work day was 63 minutes with standard deviation 2.1 minutes. Construct
a 99% confidence interval for the mean number of minutes the office workers spend browsing the
web.
