Use z scores to compare the given values. The tallest living man at one time had a height of 245 cm. The shortest living man at that time had a height of 66.4 cm. Heights of men at that time had a mean of 176.91 cm and a standard deviation of 6.51 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.

Researchers measured the data speeds for a particular smartphone carrier at 50 airports. The highest speed measured was 77.7 Mbps. The complete list of 50 data speeds has a mean of x = 18.55 Mbps and a standard deviation of s=31.38 Mbps. a. What is the difference between carrier's highest data speed and the mean of all 50 data speeds? b. How many standard deviations is that [the difference found in part (a)]? c. Convert the carrier's highest data speed to a z score. d. If we consider data speeds that convert to z scores between 2 and 2 to be neither significantly low nor significantly high, is the carrier's highest data speed significant? a. The difference is Mbps. (Type an integer or a decimal. Do not round.)
