the manager of a store counted the number of sales during a 60-hour week-this is the frequency distrubution:
______________________________________
number of     number of       relative
sales/hr      occurrences     frequency
_______________________________________
   6                25        25/60       number of occurrences add up to 60
   7                20        20/60       so that's 60hrs/wk
   8                10        10/60
