An engineer is going to redesign an ejection seat for an airplane. The seat was designed for pilots weighing between 120 18 and 181 18. The new population of plots has normally distributed weights with mean of 125 lb and a standard deviation of 30.2 lb. Click here to view page 1 of the standard normal distribution. Click here to view page 2 of the standard normal distribution. a. If a pilot is randomly selected, find the probability that his weight is between 120 lb and 181 lb. The probability is approximately (Round to four decimal places as needed.)

b. If 35 different pilots are randomly selected find the probality that their mean weight is between 130 Ib and 181 Ib

the probability is approximately - round to four decimal places as needed

**Question:**

Which part should be prioritized based on the importance of seat performance?

**Options:**

- **A.** Part (a) because the seat performance for a single pilot is more important.

- **B.** Part (a) because the seat performance for a sample of pilots is more important.

- **C.** Part (b) because the seat performance for a sample of pilots is more important.

- **D.** Part (b) because the seat performance for a single pilot is more important.

**Explanation:**

There are no graphs or diagrams present in the image. This question seems to relate to evaluating which aspect of seat performance should be prioritized, either focusing on individual pilots or a sample of pilots.

**Redesigning an Ejection Seat**

An engineer is tasked with redesigning an ejection seat for an airplane. The current seat accommodates pilots weighing between 120 lb and 181 lb. The new population of pilots has weights that follow a normal distribution, with a mean of 125 lb and a standard deviation of 30.2 lb. 

To understand this better, you can view additional resources:
- [Page 1 of the Standard Normal Distribution](#)
- [Page 2 of the Standard Normal Distribution](#)

**Problem:**

a. If a pilot is randomly selected, what is the probability that his weight is between 120 lb and 181 lb?

To find this, calculate the probability and round your answer to four decimal places. 

**Note:**

The text assumes familiarity with concepts such as the standard normal distribution and requires calculating probabilities based on these statistical parameters.
