soldi70 [24.7K]

Answer:

(C) They are the same

Step-by-step explanation:

The coefficient of variation CV is given by the following formula:

CV = \frac{\sigma}{\mu}

In which \sigma is the standard deviation and \mu is the mean.

Bob's weight has a mean of 200 pounds with a standard deviation of 16 pounds

This means that \sigma = 16, \mu = 200.

So his coefficient of variation is

CV = \frac{16}{200} = 0.08

Mary's weight has a mean of 125 pounds with a standard deviation of 10 pounds.

This means that \sigma = 10, \mu = 125

So her coefficient of variation is

CV = \frac{10}{125} = 0.08

They have the same coefficient of variation, so the correct answer is.

(C) They are the same
