Male's have an average height of 69.77 inches with a standard deviation of 3.48 inches and females have a mean height of 63.77 inches with a standard deviation of 2.91 inches. Who would be considered taller for their respective gender, president Obama at 73 inches or Michelle Obama at 71 inches tall?
Why not put on your thinking cap? Where's your effort? This is really not more than a basic math problem.
How many standard deviations up from the mean is each?
