Refer to the Business and Society (March 2011) study on the sustainability behaviors of CPA corporations, Exercise 1.28.
Corporate sustainability, recall, refers to business practices designed around social and environmental considerations. Data on the level of support for corporate sustainability were obtained for 992 senior managers. Level of support was measured quantitatively. Simulation was used to convert the data from the study to a scale ranging from 0 to 160 points, where higher point values indicate a higher level of support for sustainability.
a. A histogram for level of support for sustainability is shown next. What type of histogram is produced, frequency or relative frequency?
b. Use the graph to estimate the percentage of the 992 senior managers who reported a high (100 points or greater) level of support for corporate sustainability.
