One of the tallest living men has a height of 250 cm. One of the tallest living women is 232 cm tall, Heights of men have a mean of 176 cm and a standard deviation of 7 cm Heights of women have a mean of 159 cm and a standard deviation of 3 cm. Relative to the population of the same gender, who is taller? Explain. Choose the correct answer below. O A. The woman is relatively taller because the z score for her height is greater than the z score for the man's height. O B. The woman is relatively taller because the z score for her height is less than the z score for the man's height. O C. The man is relatively taller because the z score for his height is less than the z score for the woman's height. O D. The man is relatively taller because the z score for his height is greater than the z score for the woman's height

Researchers measured the data speeds for a particular smartphone carrier at 50 airports. The highest speed measured was 77.977.9 Mbps. The complete list of 50 data speeds has a mean of x overbarxequals=17.5417.54 Mbps and a standard deviation of sequals=18.9718.97 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 minus−2 and 2 to be neither significantly low nor significantly​ high, is the​ carrier's highest data speed​ significant?
