Aconstruction elevator can carry at most 2,320 pounds. if the elevator operator weighs 195 pounds and each palette of roofing material weighs 425 pounds, what is the maximum number of palettes of roofing material that the elevator can carry in one trip?
4.5
5
6
9.7

Subtract 195 from 2,320 to get 2,125 and then divide that by 425 to get 5 pallets

The major difference is that a histogram is only used to plot the frequency of score occurrences in a continuous data set that has been divided into classes, called bins.  bar charts, on the other hand, can be used for a great deal of other types ofvariables  including  ordinal  andnominal  data sets.
