In some reports, the mean and coefficient of variation are given. For instance, one report gives the average number of physician visits by males per year. The average reported is 3.3, and the reported coefficient of variation is 2.9%. Use this information to determine the standard deviation of the annual number of visits to physicians made by males. (Round your answer to three decimal places.)

Solution

Sol)

coefficient of variation is 2.9% and average reported is 3.3

coefficient of variation = ((Standard deviation) / mean) *100

Standard deviation = (2.9*3.3)/100 = 9.57

Standard deviation =  9.57
