An engineer is going to redesign an ejection seat for an airplane. The seat was designed for pilots weighing between 140 lb and 181 lb. The new population of pilots has normally distributed weights with a mean of 145 lb and a standard deviation of 30.3 lb. a. If a pilot is randomly selected, find the probability that his weight is between 140 lb and 181 lb.The probability is approximately _______ (Round to four decimal places as needed.)
a. If a pilot is randomly selected, find the probability that his weight is between 150 150 lb and 201 201 lb. The probability is approximately . 5393 .5393. (Round to four decimal places as needed.) b. If 36 36 different pilots are randomly selected, find the probability that their mean weight is between 150 150 lb and 201 201 lb. The probability is approximately nothing . (Round to four decimal places as needed.)
A continuous random variable is uniformly distributed between 50 and 130. a. What is the probability a randomly selected value will be greater than 102? b. What is the probability a randomly selected value will be less than 78? c. What is the probability a randomly selected value will be between 78 and 102?
An engineer is going to redesign an ejection seat for an airplane. The seat was designed for pilots weighing between 130 lb and 181 lb. The new population of pilots has normally distributed weights with a mean of 139 lb and a standard deviation of 32.2 lb a. If a pilot is randomly selected, find the probability that his weight is between 130 lb and 181 lb. The probability is approximately (Round to four decimal places as needed.) b. If...
A continuous random variable is uniformly distributed between 100 and 150. a. What is the probability a randomly selected value will be greater than 130? P(x > 130) = ______ . (Simplify your answer. Give as decimal.) b. What is the probability a randomly selected value will be less than 120? P(x < 120) = ______ . (Simplify your answer. Give as decimal.) c.
