Question 10 • AZ-Common Core Algebra II B

Suppose the scores of seven members of a women’s golf team are 68, 62, 60, 64, 70, 66, and 72. Find the mean, median, and midrange.

Answer
A
Mean = 64, median = 64, midrange = 64
B
Mean = 65, median = 64, midrange = 66
C
Mean = 66, median = 77, midrange = 65
D
Mean = 66, median = 66, midrange = 66

Explanation

The scores add to 462, and 462 ÷ 7 = 66, so the mean is 66. In order, the scores are 60, 62, 64, 66, 68, 70, and 72; the middle score, or median, is 66. The midrange is the average of the lowest and highest scores: (60 + 72) ÷ 2 = 66. Choice D gives all three values correctly.
