Sensor Technology wishes to determine its coefficient of variation as a company over time. The firm projects the following data (in millions of dollars):

Year Profits: Expected Value Standard deviation

1 $93 $46

3 $140 $60

6 $224 $86

9 $264 $96

(a)	Compute the coefficient of variation (V) for each time period. (Round your answers to 2 decimal places.) Year Coefficient of variation 1 ? 3 ? 6 ? 9 ? b. Does the risk appear to be increasing over a period of time?
