7-E10. Revenue for January is normally distributed with mean $345.5K and standard deviation $75.9K. Based on historical seasonal patterns the revenues for the other months are higher than January by the amounts in the table below. So for instance, February revenue is normally distribution but with a mean and standard deviation 6% higher than in January.
