Question

Consider the following data,which represent the number of miles that employees commute from home to work each day.There are two samples: one for males and one for females. Males:  Females:  The coefficient of variation of commute miles for the males is:
A)approximately 76 percent. 
B)about 7.8. 
C)approximately 61.5. 
D)about 67 percent.

To calculate the coefficient of variation (CV), we first need to find the mean and standard deviation of the data set. For the males, the mean commute distance is 12.125 miles with a standard deviation of 9.25 miles.

CV = (standard deviation / mean) x 100%
CV = (9.25 / 12.125) x 100%
CV = 0.762 x 100%
CV = 76.2%

Therefore, the answer is approximately 76 percent, which is option A.
