I think your question is missed of key information, allow me to add in and hope it will fit the original one. Please have a look at the attached photo

Basically, interquartile range represents the width or "dispersion" of the set. [1] The interquartile range is determined by the difference between the top quartile (25% highest) and lower quartile (25% lowest) point of the data set.

From the picture, we can find that:

• The interquartile range of the bus drivers is: 20 -10 = 10
• The interquartile range of the teachers is: 30 -15 = 15

So the interquartile range of the distances for the bus drivers is 5 miles less than the interquartile range of the distances for the teachers.

We choose C
