Question

Growth factors for the population of Chattanooga in the past two years have been 8 and 12. The geometric mean has a value of
A) 20. 
B) . 
C) . 
D) 96.

Quizplus · Accepted Answer

The formula for calculating the geometric mean is:
Geometric mean = (growth factor 1 x growth factor 2 ... x growth factor n)^(1/n)
Substituting the growth factors given:
Geometric mean = (8 x 12)^(1/2) = 9.79 (rounded to two decimal places)
Therefore, the best choice is C - 11eb12c9_c6b0_2172_b394_d32dddb86fec_TB6985_11.
