Corporate sustainability of CPA firms. Refer to the Business and Society (Mar. 2011) study on the sustainability behaviors of CPA corporations, Exercise 1.26 (p. 22). Recall that corporate sustainability 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 below. What type of histogram is produced, frequency or relative frequency? 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. 10.2%

Reference: Exercise 1.26

Corporate sustainability. Corporate sustainability refers to business practices designed around social and environmental considerations (e.g., “going green”). Business and Society (Mar. 2011) published a paper on how firm size and firm type affect sustainability behaviors. A survey was sent to approximately 23,500 senior managers at CPA firms, of which 1,293 senior managers responded. (Note: It is not clear how the 23,500 senior managers were selected.) Due to missing data (incomplete survey answers), only 992 surveys were analyzed. These data were used to infer whether larger firms are more likely to report sustainability policies than smaller firms and whether public firms are more likely to report sustainability policies than private firms.
