Question

The heights, in inches, of flowers in a garden have the density function shown in the following figure. The median height is 
A)less than 20 inches. 
B)equal to 20 inches. 
C)greater than 20 inches.

Quizplus · Accepted Answer

Based on the density function shown in the figure, the peak of the distribution occurs between 20 and 25 inches. Therefore, it is likely that the median height is also in this range. Since the density function is skewed to the right, the median height will be less than the mean height, which is about 22 inches. Therefore, the best choice is C, greater than 20 inches.
