Question

A study was performed on the sustainability behaviors of corporations. Corporate sustainability refers to business practices designed around social and environmental considerations. Data on the level of support for corporate sustainability were obtained for 812 senior managers. Level of support was measured quantitatively. Simulation was used to convert the data to a scale ranging from 0 to 160 points, where higher point values indicate a higher level of support for sustainability. This converted data was used to make the accompanying histogram. Complete parts a and b below. Click the icon to view the histogram. a. What type of histogram is given, frequency or relative frequency? O A. Frequency, because the percents on the vertical axis represent the total number of observations falling into each class B. Frequency, because the levels on the horizontal axis represent the numbers of observations that fall into each class C. Relative frequency, because the levels on the horizontal axis represent the proportions of the total number of observations falling into each class D. Relative frequency, because the percents on the vertical axis represent the proportions of the total number of observations falling into each class

2. Use the graph to estimate the percentage of the 812 who reported a high(100 points or greater) level of support for corporate sustainbility

Answer 1

D. Relative frequency, because the percents on the vertical axis represent the proportion of the total number of observations falling into each class.

As we can see on the vertical axis the values are in percent. The horizontal axis represents the bins. The bars in histogram represent the proportion of observations falling in each bin. Since the value value is proportion of the total it is relative frequency
