Question
**Problem Statement:**

Assume the random variable \( X \) is normally distributed with a mean \( \mu = 50 \) and a standard deviation \( \sigma = 7 \). Compute the probability. Be sure to draw a normal curve with the area corresponding to the probability shaded.

\[ P(35 < X < 65) \]

**Question:**

Which of the following normal curves corresponds to \( P(35 < X < 65) \)?

**Options:**

- **A.** 
  - Description: The graph is a normal distribution curve centered at 50, with the area between 35 and 65 shaded in blue. This represents the probability \( P(35 < X < 65) \) under a symmetric curve where the total shaded area covers the region bounded by 35 on the left and 65 on the right.

- **B.** 
  - Description: This graph is similar to curve A, with a normal distribution curve centered at 50. The entire area under the curve from 35 to 65 is shaded in blue, covering the same region as A.

- **C.**
  - Description: The normal distribution curve is centered at 50, but only the tails extending beyond 35 and 65 are shaded in blue. This indicates areas outside the range of interest \( 35 < X < 65 \), which is incorrect for the given probability.

**Correct Choice:** 

The correct choice for illustrating \( P(35 < X < 65) \) is both A and B, as they show the appropriate shaded region between 35 and 65 under the normal curve.
