The table shows the distribution of the masses of the actors in a theatre group. Draw a histogram to show the data. Mass in kilograms m Frequency 60 ⩽ m < 63 9 63 ⩽ m < 64 12 64 ⩽ m < 65 15 65 ⩽ m < 66 17 66 ⩽ m < 68 10 68 ⩽ m < 72 8

As the class widths are unequal, we have to find the frequency density of each class to draw the histogram. The frequency density table looks like: Mass in kilograms m Frequency Class width c w Frequency density f ÷ c w 60 ⩽ m < 63 9 3 9 3 = 3 63 ⩽ m < 64 12 1 12 1 = 12 64 ⩽ m < 65 15 1 15 1 = 15 65 ⩽ m < 66 17 1 17 1 = 17 66 ⩽ m < 68 10 2 10 2 = 5 68 ⩽ m < 72 8 4 8 4 = 2 The histogram is shown below. The mass in kilogram of the actors is represented in x - axis and corresponding frequency density is represented in y - axis.
