an engineer is going to redesign an ejection seat for an airplane the seat was designed for Pilots weighing 150 lb and 191 lb the new population of Pilots has normally distributed weights with a mean of 158 lb and a standard deviation of 33.9 pounds if a pilot is randomly selected find the probability that his weight is between 150 lb and 191 lb ..the probability is approximately ? If 33 different Pilots are randomly selected find the probability that their mean weight is between 150 lb and 191 lb...the probability is approximately ?when redesigning the ejection seat which probability is more relevant?

An engineer is going to redesign an ejection seat for an airplane. The seat was designed for pilots weighing between 150 lb and 201 lb. The new population of pilots has normally distributed weights with a mean of 157 lb and a standard deviation of 27.5 lb. An engineer is going to redesign an ejection seat for an airplane. The seat was designed for pilots weighing between 150 lb and 201 lb. The new population of pilots has normally distributed...
#9can you help me solve this problem step by step, An engineer is going to redesign an ejection seat for an airplane. The seat was designed for pilots weighing between 120 lb. and 161 lb. The new population of pilots has normally distributed weights with a mean of 126 lb. and a standard deviation of 29.8 lb. If a pilot is randomly selected, find the probability that his weigh is between 120 lb. and 1761 lb. A, if a pilot...
Name: Be sure to show your work for potential partial credit! 1. An engineer is going to redesign an ejection seat for an airplane. The seat was designed for pilots weighing between 130 lb and 191 lb. The new population of pilots has normally distributed weights with a mean of 138 lb and a standard deviation of 30.9 lb. a. If a pilot is randomly selected, find the probability that his weight is between 130 Ib and 191 lb. (Round...
1) A survey found that women's heights are normally distributed with mean 63.6 in and standard deviation 3.7 in. The survey also found that men's heights are normally distributed with mean 69.7 in and standard deviation 3.4 in. Consider an executive jet that seats six with a doorway height of 56.5 in Complete parts (a) through (c) below. a. What percentage of adult men can fit through the door without bending? The percentage of men who can fit without bending...
4. A lift has an occupancy warning of no more than 25 people and of total weight no more than 1950kg. For a population of users, suppose weights are normally distributed with mean 75kg and standard deviation 10kg (a) What is the probability that the total weight of a random sample of 25 people from the population exceeds 1950kg? (b) Calculate the probability that a random sample of 24 people sets the alarm off. (c) Suppose people carry things with...
