O B. "he lengths of the rows are similar to the heights of bars in a histogram; longer rows of data correspond to smaller frequencies. 0 C. _he lengths of the rows are similar to the widths of bars in a histogram; longer rows of data correspond to smaller frequencies. O D. "he lengths of the rows are similar to the widths of bars in a histogram; longer rows of data correspond to higher frequencies. A frequency table of grades has ve classes (A, B, C, D, F} with frequencies of 5, 14, 13, 5, and 3 respectively. Using percentages, what are the relative frequencies of the ve classes?
