Answer:
The box plot is shown below.
Step-by-step explanation:
The given data set is
27, 20, 14, 15, 16, 17, 18, 19, 18, 19, 21
Arrange the data set in ascending order.
14, 15, 16, 17, 18, 18, 19, 19, 20, 21, 27
Divide the data set in two equal parts.
(14, 15, 16, 17, 18), 18, (19, 19, 20, 21, 27)
Divide each parenthesis in two equal parts.
(14, 15), 16, (17, 18), 18, (19, 19), 20, (21, 27)
Now, we get
The end points of line are 14 and 27. The ends of box plots are 16 and 20. A line inside the box at 18.
