Complete parts (a) through (c) below. Click the icon to view the side-by-side bar graph. (a) Does the graph suggest that grade inflation is a problem in colleges? A. Yes, because the GPAS increased over time for all schools. B. No, because nothing can be concluded about individual GPAS from the averages. C. No, because the GPAS are different for each time period. D. Yes, because the GPAS are greater for private schools for every time period. (b) In public schools, the average GPA was 2.86 in 1991-1992 and 3.02 in 2006-2007.
