Question

Beanstalks Beanstalk Clubs are social clubs for very
tall people. To join, a man must be over 6′2′′ tall, and a
woman over 5′10′′. The National Health Survey suggests
that heights of adults may be Normally distributed, with
mean heights of 69.1′′ for men and 64.0′′ for women. The
respective standard deviations are 2.8′′ and 2.5′′.
a) You are probably not surprised to learn that men
are generally taller than women, but what does the
greater standard deviation for men’s heights indicate?

b) Who are more likely to qualify for Beanstalk mem-
bership, men or women? Explain.

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
