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?
The solution compares the variation of adult heights and weights via hypothesis testing.
