Answer:
B
Explanation:
A "box and whisker" plot is a visual representation of the 5-number summary of a data set. It shows you the minimum, maximum, median, and the 1st and 3rd quartile values.
__
The given data is sorted, so the first value (5) and the last value (19) will be the ends of the whiskers. (Eliminates choice A)
There are 15 data values, so the 8th one is the middle one, the median. That value is 10, and corresponds to the vertical line in the box. (Eliminates choices C and D.)
When the median is removed from the data set, it is divided into two parts, each containing 7 data values. The middle (4th) one of each of these are the 1st and 3rd quartiles, the ends of the box. They are 8 and 17, confirming that choice B is the correct box and whisker plot.
