An engineer is going to redesign an ejection seat for an airplane. The seat was designed for pilots weighing between 130 lb and 171 lb. The new population of pilots has normally distributed weights with a mean of 136 lb and a standard deviation of 26.8 lb. Click here to view page 1 of the standard normal distribution.

Question
**Redesigning an Ejection Seat for Aircraft: Statistical Analysis** An engineer is tasked with redesigning an ejection seat for an airplane. The current seat is tailored for pilots weighing between 130 lb and 171 lb. The latest data on the population of pilots shows that their weights are normally distributed, with a mean weight of 136 lb and a standard deviation of 26.8 lb. - **Useful Resources:** - [Page 1 of the Standard Normal Distribution](#) - [Page 2 of the Standard Normal Distribution](#) **Problem: Calculate the Probability of Pilot Weight** a. Determine the probability that a randomly selected pilot will weigh between 130 lb and 171 lb. - Required precision: Round your answer to four decimal places. **Solution:** To find this probability, you would typically use the standard normal distribution and convert the weights to z-scores. You can then use standard normal distribution tables or a calculator to find the probabilities associated with these z-scores.
