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 Enter., 1997: 365-368) gave the following cumulative percentages (read from a graph) for lire loads in a sample of 388 rooms:
a. Construct a relative frequency histogram and comment on interesting features.b. What proportion of fire loads are less than 600? At least 1200?c. What proportion of the loads are between 600 and 1200?
An article in the journal Air and Waste (Update on Ozone Trends in California's South Coast Air
Basin, Vol. 43, 1993) investigated the ozone levels in the South Coast Air Basin of California for
the years 1976-1991. The author believes that the number of days the ozone levels exceeded 0.20
ppm (the response) depends on the seasonal meteorological index, which is the seasonal average
850-millibar Temperature (the predictor). The following table gives the data.
