Twelve randomly chosen students were asked how many times they had missed class during a certain semester, with this result: 3, 2, 1, 2, 1, 5, 9, 1, 2, 3, 3, 10. The geometric mean is:
A) $\sqrt [ 12 ] { 42 }$
B)2.604
C)1.517
D) $\sqrt [ 2 ] { 97200 }$

Quizplus · Accepted Answer

The formula for geometric mean is:
gm = (x1 * x2 * ... * xn)^(1/n)

Using the given values, we get:

gm = (3 * 2 * 1 * 2 * 1 * 5 * 9 * 1 * 2 * 3 * 3 * 10)^(1/12)
gm = (4860)^(1/12)
gm = 2.604

Therefore, the best choice is B.
