Based on daily measurements, bob's weight has a mean of 200 pounds with a standard deviation of 16 pounds, while mary's weight has a mean of 125 pounds with a standard deviation of 15 pounds. who has the smaller relative variation?
Accepted Solution
A:
200/16 = 12.5, and 125/15 = 8.33
When the standard deviations are compared to the mean body weights, it's obvious that Mary's weight varies less in relative terms than Bob's.
