Problem 32E

Fire load (MJ/m2)is the heat energy that could be released per square meter of floor area by combustion of contents and the structure itself. The article “Fire Loads in Office Buildings” (?J. of Structural Engr., ?1997: 365–368) gave the following cumulative percentages (read from a graph) for fire loads in a sample of 388 rooms: a.? ?Construct a relative frequency histogram and comment on interesting features. b.? hat proportion of fire loads are less than 600? At least 1200? c.? hat proportion of the loads are between 600 and 1200?
