Assume that the random variable X is normally distributed, with mean μ = 45 and standard deviation σ = 10. Compute the probability P(55 < X < 70). Be sure to draw a normal curve with the area corresponding to the probability shaded.

Draw a normal curve with the area corresponding to the probability shaded. Choose the correct graph below.

Options:
- **A:** A normal distribution curve with the mean at 45. The shaded area starts at the mean (45) and extends to 55.
- **B:** A normal distribution curve with the mean at 45. The entire area from the mean (45) to the right (including beyond 70) is shaded.
- **C:** A normal distribution curve with the mean at 45. The shaded area is between 55 and 70.

The correct graph is option **C.**

\[ P(55 < X < 70) = \text{(Round to four decimal places as needed.)} \]
