The side-by-side bar graph available below shows the approximate average grade point average years 1991-1992, 1996-1997, 2001-2002, and 2006-2007 for colleges and universities. Complet 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? OA. Yes, because the GPAS increased over time for all schools. B. No, because nothing can be concluded about individual GPAS from the averages. OC. No, because the GPAS are different for each time period. O 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. In private

The side-by-side bar graph available below shows the approximate average grade point average for the years 1991-1992, 1996-1997, 2001-2002, and 2006-2007 for colleges and universities. 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. In private schools, the average GPA was 3.09 in 1991-1992 and 3.30 in 2006-2007. Determine the percentage increase in GPAs for public schools from 1991 to 2006.
