Recall that a relative frequency histogram is used to graph quantitative data. Classes are chosen to divide the range of values into equal-length subintervals, then plott along the horizontal axis. A bar is drawn for each class with height equal to the relative frequency for that class. To create a relative frequency histogram, first summarize the following data in a frequency table. 1 2 3 4 5 6 7 8 Class Class Boundaries 9 1.3 10 14.7 11 14.9 4.4 2.7 32.3 10.9 9.0 1.6 9.0 16.7 7.4 4.1 18.4 0.2 6.1 13.5 1.0 2.4 Since the measurements are all between the values 0 and 33, it will be convenient to choose 11 class intervals of length 3. Using the given data, tally the values within each class interval to determine the frequency of each class, and fill in the following table. 0 to <3 3 to < 6 3.5 11.2 18.0 26.7 3.7 6 to < 9 9 to 12 12 to 15 15 to 18 18 to 21 21 to 24 24 to 27 27 to < 30 30 to < 33 1 1 2.4 2 1 10 8.2 19.2 Frequency 5 1 18.0 4 1 X x X ✓ 2.0 6.6 3.9 1.6 x 5.9 4.3 3.3 1.2 9.4 0.2 8.7 24.0 8.3 0.3 1.3 1.4 8.2 5.8 12.6 23.1 5.6 0.2

Recall that a relative frequency histogram is used to graph quantitative data. Classes are chosen to divide the range of values into equal-length subintervals, then plotted along the horizontal axis. A bar is drawn for each class with height equal to the relative frequency for that class. To create a relative frequency histogram, first summarize the following data in a frequency table. 1 N 2 3 4 5 6 7 Class Class Boundaries 8 9 1.3 10 11 14.7 9.0 16.7 4.1 14.9 4.4 2.7 32.3 10.9 9.0 9.0 1.6 18.4 1.0 2.4 2.4 18.0 Since the measurements are all between the values 0 and 33, it will be convenient to choose 11 class intervals of length 3. Using the given data, tally the values within each class interval to determine the frequency of each class, and fill in the following table. 0 to <3 3.5 11.2 18.0 26.7 3.7 3 to 6 6 to 9 9 to 12 12 to < 15 15 to 18 18 to 21 21 to 24 24 to 27 0.2 6.1 13.5 27 to < 30 30 to 33 7.4 8.2 19.2 1 1 2 1 Frequency 10 5 1 4 1 X X 9.4 X 8.7 X 2.0 6.6 3.9 5.9 4.3 3.3 0.2 24.0 1.6 1.2 8.3 0.3 1.3 1.4 8.2 5.8 12.6 23.1 5.6 0.2
