Corporate sustainability of CPA firms. Refer to the Business and Society (Mar. 2011) study on the sustainability behaviors of CPA corporations, Exercise 2.36

(pp. 78).

Recall that the level of support for corporate sustainability

(measured on a quantitative scale ranging from 0 to 160 points) was obtained for each 992 senior managers at CPA firms. Numerical measures of both central tendency and variation for level of support are shown in the MINITAB printout below. Give an estimate of the number of the 992 senior managers who have support levels between 41 and 95 points. (Use the histogram in Exercise 2.36 to help you decide which rule to apply.)
