Using the box and whisker plot, it is found that the percent of those in the survey get at least 90 milligrams of Vitamin C is of:

A. between 25% and 50%.

What does a box and whisker plot shows?

A box and whisker plot shows three things:

  • The 25th percentile, which is the median of the bottom 50%.
  • The median.
  • The 75th percentile, which is the median of the upper 50%.

In this problem, we have that: P25 = 80, P50 = 85, P75 = 95.

Hence, 90 is between the median and the 75th percentile, which means that between 25% and 50% of those in the survey get at least 90 milligrams of Vitamin C, and option A is correct.
