If the distribution of sales is thought to be symmetric with very little variation, then:

B) the width of the box in a box and whisker plot will be very wide but the whisker will be very short

D) none of these
E) all of these

If the distribution is symmetric with little variation, the median (second quartile) should be the center of the box in the box and whisker plot. As the distribution is symmetric, the quartiles should be equidistant from the median, resulting in the edges of the box being approximately equidistant from the median.
