Use z scores to compare the given values. The tallest living man at one time had a height of 239 cm. The shortest living man at that time had a height of 133.8 cm. Heights of men at that time had a mean of 174.58 cm and a standard deviation of 6.12 cm. Which of these two men had the height that was more extreme? Question content area bottom Part 1 Since the z score for the tallest man is z=enter your response here and the z score for the shortest man is z=enter your response here, the ▼ shortest tallest man had the height that was more extreme.
