Explanation:

Step1: Arrange data in ascending order

50, 60, 70, 72, 74, 80, 82, 83, 90, 91, 100

Step2: Find the median (Q2)

There are 11 data - points. The median is the 6th value. So Q2 = 80.

Step3: Find the lower half of data

50, 60, 70, 72, 74. The median of the lower half (Q1) is 70.

Step4: Find the upper half of data

82, 83, 90, 91, 100. The median of the upper half (Q3) is 90.

Step5: Identify the minimum and maximum

The minimum is 50 and the maximum is 100.
A box - and - whisker plot has a box from Q1 to Q3 with a line at Q2, and whiskers from the minimum to Q1 and from Q3 to the maximum. The correct box - and - whisker plot should have the box starting at 70, ending at 90, with a line inside the box at 80, and whiskers going to 50 and 100.

Answer:

The box - and - whisker plot with the box starting at 70, ending at 90, a line inside the box at 80, and whiskers extending to 50 and 100.
