A local industrial company has two departments. In the larger department, about 45 sales invoices are completed each day; in the smaller department about 15 invoices are completed each day. About 50% of all sales invoices completed in each department specify discounts from the companys list prices. However, the exact percentage varies from day to day. Sometimes it may be higher than 50%, while other times it might be lower.

For a period of one year, and for each department, a member of the internal audit staff kept track of the number of days on which more than 60% of the sales invoices specified discounts.

Required: Discuss which department you think showed the greater number of such days - The larger department, the smaller department, or about the same and why?
