An engineer is going to redesign an ejection seat for an airplane. The seat was designed for pilots weighing between 140 lb and 201 lb. The new population of pilots has normally distributed weights with a mean of 149 lb and a standard deviation of 32.2 lb.
A. If a pilot is randomly selected, find the probability that his weight is between 140 lb and 201 lb.
The probability is approximately:
B. If 35 different pilots are randomly selected, find the probability that their mean weight is between 140 lb and 201 lb.
The probability is approximately:

Cor d? ? me ? max recorded the heights of 500 male humans. he found that the heights were normally distributed around a mean of 177 centimeters. which statements about max’s data must be true? a) the median of max’s data is 250 b) more than half of the data points max recorded were 177 centimeters. c) a data point chosen at random is as likely to be above the mean as it is to be below the mean. d) every height within three standard deviations of the mean is equally likely to be chosen if a data point is selected at random.
