The graph shows the weights, in
kilograms, of emperor penguins at a zoo. Is the range of the weights 24
kilograms?
The range of any data set can
be calculated by subtracting the smallest value from the largest value. As the weights on the line plot
are already in order, we can see that the smallest value is 23 kilograms. The largest value is 49
kilograms. We can therefore calculate the
range by subtracting 23 from 49. 40 minus 20 is equal to 20, and
nine minus three is equal to six. Therefore, 49 minus 23 equals
26. The range of values of the
emperor penguins is 26 kilograms. This means that the answer to
the question “Is the range of the weights 24 kilograms?” is no.
