问题 Questions are based on the following data.

For the 55-64 age-group in 1998, the average (arithmetic mean) number of workhours lost per occupational injury was 48.5. If a workweek is 40 work-hours, which of the following is closets to the total number of workweeks lost due to occupational injuries in the 55-64 age-group in 1998?
选项 A、4,500
B、5,200
C、5,500
D、5,900
E、6,300
答案E
解析 55到64岁共计人口为5.2 thousands，所以总共工时损失为5200×48.5=252200小时，换算成工作周(workweek)是252200/40=6305 workweeks。故答案为E。
