Question

Feel free to only do the geometric means. I can figure out the arithmetic means. Thanks!

The mean defined in the text is sometimes called the arithmetic mean to distinguish it from other possible means. For example, a different mean, called the geometric mean (G.M.), is used in business and economics for finding average rates of change, average rates of growth, or average ratios. This mean is defined to be the nth root of the product of the numbers. For example, the geometric mean of 4, 5, and 6 is = (4-5-6)1/3 -V120 G.M. 4.9. (a) Find the arithmetic and geometric means for the numbers 3, 4, 5, 7, 7, 8, and 9. (Round your answers to one decimal place.) arithmetic mean geometric mean 2.0%, and 0 8%. Compare the arithmetic and geometric means. Round your answers to two decimal places. b) The growth rates for three cities are 1.7% arithmetic mean geometric mean

Explanation / Answer

a) geometric mean =(3*4*5*7*7*8*9)1/7=5.8

b) geometric mean =(1.7*2*0.8)1/3 =1.40 ( please try 1.50 if this does not work and I will explain)
