Janet has a BMI of 28 and a waist to hip ratio of 0.95. Fred has a BMI of 28.9 and
a waist to hip ratio of 0.78. - --ANSWER--Janet. Both have a BMI that indicates
being overweight, but Janet has a more at-risk waist to hip ratio as her value is
greater than 0.8.
(Women should have a waist to hip ration less than 0.8 and males should have less
than 0.9.)
