(c) What height is exceeded by 25% of the men? (d)...
In the United States, men’s heights have mean of 69 inches, and standard deviation of 3 inches. Assume height is normally distributed. What is the probability that a randomly selected male will be between 66.45 and 72.75 inches tall?
Men’s heights are normally distributed with a mean of 69.0 inches and a standard deviation of 2.8 inches. a) What is the probability that a man selected at random is at least 72 inches tall? Round the answer to 4 decimal places. b) The Mark VI monorail used at Disney World has doors with a height of 72 inches. What doorway height would allow 98% of adult men to fit without bending?
Men’s heights are normally distributed with a mean of 68.5 inches and standard deviation 2.2 inches. The U.S. Navy requires that fighter pilots have heights between 62 in. and 78 in. If the Navy changes the height requirements so that all men whose heights fall within the middle 82% of the population are eligible to be fighter pilots, what are the new requirements for men? Please show all your work and write your answer in a complete sentence. (7 points)
