A student conducted a study on the height and weight of adult males. She collected data from 40 adult males and found that average height is 68.34 inches with a standard deviation of 14.02 inches, and the average weight is 172.55 lbs. with a standard deviation of 26.33lbs. Based on the above values of the standard deviations, she stated the following: "The height of adult males has considerably less variation than their weight" Do you support her conclusion? Why or why not?© BrainMass Inc. brainmass.com June 3, 2020, 7:41 pm ad1c9bdddf
