## Normal Distribution Problems

### Given:
Mean (\(\mu\)) = 27.8
Standard deviation (\(\sigma\)) = 9.2

For each problem, label the x-axis and shade the Normal curve appropriately. Find the z-score rounded to the hundredth place. Use the table to find the area of the shaded region, which represents the probability.

#### a. \(x\) is less than 30.4

- **z = ___________**
- **Probability (prob) = ___________**

**Diagram:**
A normal distribution curve is shown with the left side shaded, indicating the area less than 30.4.

#### b. \(x\) is greater than 24.0

- **z = ___________**
- **Probability (prob) = ___________**

**Diagram:**
A normal distribution curve is shown with the right side shaded, indicating the area greater than 24.0.

#### c. Area is between \(x = 20.0\) and \(x = 32.0\)

- **z = ___________**
- **Probability (prob) = ___________**

**Diagram:**
A normal distribution curve is shown with an area in the middle shaded, indicating the area between 20.0 and 32.0.
