Assume the random variable X is normally distributed with mean μ = 50 and standard deviation σ = 7. Compute the probability. Be sure to draw a normal curve with the area corresponding to the probability shaded. P(55 ≤ X ≤ 66) **Which of the following normal curves corresponds to P(55 ≤ X ≤ 66)?** 1. **Graph A**: A normal distribution curve is shown with a mean at 50. The shaded area spans from 55 to 66. The left portion of the distribution, below 55, is not shaded, indicating the probability being calculated is for values of X between 55 and 66. 2. **Graph B**: A normal distribution curve centered around a higher value than 50. The shaded area spans the entire distribution tail from 55 to 66. 3. **Graph C**: This graph depicts the correct normal distribution centered at 50, with shading between 55 and 66, matching the area of interest accurately.
