appearance for the Manistee National Forest festival. 1. a.) Both men are pictured above with Star Wars characters. Assume that heights of men are normally distributed, with a mean of 68.6 inches and a standard deviation of 2.8 inches. Find the z-scores for these two remarkable men at the time of their deaths. b.) Could you argue that one man is “more unusual” than the other, based on their z-scores? Why?
Chandra Bahadur Dangi (1939-2015), who stood at 21.5 inches was the shortest (adult) person in
human history for whom there is irrefutable evidence. Three of his five brothers were less than
four feet tall, while his two sisters and two other brothers were of normal height. Before being
recognized by the Guinness Book of World Records, he had never left his village in Nepal, and
after awarded the title of world’s shortest, he expressed his wish to travel the world.
Robert Pershing Wadlow (1918-1940) was the tallest person in history for whom there is
irrefutable evidence. Born a healthy 8 pound 6 ounces, in Alton Illinois, he grew at a rapid pace
and at the age of eight he was a whopping 6 feet and 2 inches and 195 pounds. His extraordinary
height was attributed to an overactive pituitary gland, which produced an excess of the growth
hormone. Wadlow reached a towering 8 feet and 11 inches and weighed 485 lbs. at his death of
the age of 22 from infection caused by a faulty brace irritating his ankle at a professional
appearance for the Manistee National Forest festival.
