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

To find the geometric mean, we need to multiply all the numbers and then take the nth root of the result, where n is the total number of values (in this case, 12).

3 x 2 x 1 x 2 x 1 x 5 x 9 x 1 x 2 x 3 x 3 x 10 = 16,200

The 12th root of 16,200 is approximately 2.604, which is answer choice B.
