a. Find the relative frequencies for each observation. Write them in the charts (use 2 decimal places). b. Using either a graphing calculator, computer, or by hand, use the frequency column to construct a histogram for each school's data. For A and B, make bar widths of one. For C, make bar widths of two. Be careful to include ALL X values in the range - even if f = 0. c. In a sentence compare the graphs for schools A and B - give at least 1 way in which they are different and 1 way they are similar. d. How does the graph for School C look different from the other two graphs and why?
