Suppose that a company's annual sales were $1,200,000 in 1999. The annual growth rate of sales from 1999 to 2000 was 16%, from 2000 to 2001 was -5%, and from 2001 to 2002 was 22%.The geometric mean growth rate of sales over this three-year period is calculated as 10.37%.

Based on the box plot, what are the range and ther interquartile range?
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 rat 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 G.M. = (4 · 5 · 6)/3 V120 z 4.9.
