An engineer is going to redesign an ejection seat for an airplane. The seat was designed for pilots weighing between 140 and 201 The new population of plots has normally distributed weights with a mean of 148 b and a sonderd deviatio Click here to view page 1 of the standard normal distribution of 32.2 lb. Click here to view cage 2 of the standard normal distribution a. If a plot is randomly selected, find the probability that his weight is between 140 and 201 The probability is approximately (Round to four decimal places as needed) b. If 40 different picts are randomly selected, find the probability that their mean weight is between 140 and 2016 The probability is approximately Mound to four decimal) When redesigning the ejection seat, which probably is mom OA Part (a) because the seat performance for a single pas more important OB. Pat (h) because the seat performance for a single pilot is more important Oc. Pan (b) because the seat performance for a sample of pits is more important Op. Part (a) because the seat perfomance for a sample of plots is more important
