airliner carries 350 passengers and has doors with a height of 74 in. Heights of men are normally distributed with a mean of 69.0 in and a standard deviation of 2.8 in. Complete parts (a) through (d). If a male passenger is randomly selected, find the probability that he can fit through the doorway without bending e probability is ound to four decimal places as needed.) If half of the 350 passengers are men, find the probability that the mean height of the 175 men is less than 74 in. he probability is Round to four decimal places as needed.) When considering the comfort and safety of passengers, which result is more relevant the probability from part (a) or the probability from part (b)? Why? DA. The probability from part (b) is more relevant because it shows the proportion of flights where the mean height of the male passengers will be less than the door height DB. The probability from part (b) is more relevant because it shows the proportion of male passengers that will not need to bend. DC. The probability from part (a) is more relevant because it shows the proportion of flights where the mean height of the male passengers will be less than the door height. DD. The probability from part (a) is more relevant because it shows the proportion of male passengers that will not need to bend.

The average speed of cars on 495 is 74 mph with a standard deviation of 6. What is the probability that a car will be traveling at least 76 mph

Evpte. If the probability of a defective bolt is 0.1, find Ta) the mean (b) the standard deviation for the distribution of defective bolts in a total of 400.

An elevator has a placard stating that the maximum capacity is 4400 lb-29 passengers. So, 29 adult male passengers can have a mean weight of up to 4400/29 = 152 pounds. Assume that weights of males are normally distributed with a mean of 180 lb and a standard deviation of 29 lb. a. Find the probability that 1 randomly selected adult male has a weight greater than 152 lb. b. Find the probability that a sample of 29 randomly selected adult males has a mean weight greater than 152 lb. c. What do you conclude about the safety of this elevator? a. The probability that 1 randomly selected adult male has a weight greater than 152 lb is ☐ (Round to four decimal places as needed.)
