What is the answer

Use z scores to compare the given values. The tallest living man at one time had a height of 243 cm. The shortest living man at that time had a height of 136.3 cm. Heights of men at that time had a mean of 174.23 cm and a standard deviation of 6.22 cm. Which of these two men had the height that was more extreme? Since the z score for the tallest man is z= and the z score for the shortest man is z= the man had the height that was more extreme. (Round to two decimal places.)
