K An engineer is going to redesign an ejection seat for an airplane. The seat was designed for pilots weighing between 140 lb and 181 lb. The new population of pilots has normally distributed weights with a mean of 148 lb and a standard deviation of 26.8 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 140 lb and 181 lb. The probability is approximately (Round to four decimal places as needed.)

**Ejection Seat Design and Probability Calculator**

An engineer is redesigning an ejection seat for an airplane. The seat was originally designed for pilots weighing between 140 lb and 181 lb. The latest population data shows that pilots' weights are normally distributed, with a mean of 148 lb and a standard deviation of 26.8 lb.

**Resources:**
- [Click here to view page 1 of the standard normal distribution](#)
- [Click here to view page 2 of the standard normal distribution](#)

**Problem:**
- **a. Calculate the Probability:**
  - Task: Find the probability that a randomly selected pilot weighs between 140 lb and 181 lb.
  
  - Enter your answer: The probability is approximately [____] (Round to four decimal places as needed).

**Instructions:**
- Use the provided standard normal distribution tables to find Z-scores for weights of 140 lb and 181 lb.
- Calculate the probability by finding the area under the normal distribution curve between these Z-scores.
  
To solve this problem, familiarize yourself with normal distribution concepts, Z-scores, and how to use statistical tables effectively.
