Suppose that the mean height ofGrade 11 male students in a certainschool is 170 cm, and that theheights are normally distributed. Arandom sample of 16 male studentswas selected, and their standarddeviation of 4 cm. What is theprobability that the mean height ofa random sample of 16 students willbe between 168 and 172 cm?a. 0.9360O b. 0.9362c. 0.9363d. 0.9361

Suppose that an airline uses a seat width of 16.7 in. Assume that men have hip breadths that are normally distributed with a mean of 14.2 inches, and a standard deviation of 1in. Find the probability that if an individual man is randomly selected that his hip breadths will be greater than 16.7 in.
Based on data from the National Health Survey, women between the ages of 18 and 24 have an average systolic blood pressures (in mm Hg) of 114.8 with a standard deviation of 13.1.
