Find the area of the shaded region under the standard normal curve.
Title: Understanding the Standard Normal Table

The Standard Normal Table, also known as the Z-table, provides the area (probability) under the normal distribution curve up to a given z-score. The table is often used in statistics to find the probability that a statistic is observed below, above, or between values on the standard normal distribution.

### Layout

- **Columns and Rows**: The table has a vertical and horizontal axis with z-scores. The rows represent the integer and first decimal place of the z-score (e.g., 0.0, 0.1, 0.2), while the columns represent the second decimal place of the z-score (e.g., .00, .01, .02).
  
- **Z-Score**: The values in blue represent the cumulative probability for the given z-score. For example, a z-score of 0.0 corresponds to a cumulative probability of 0.5000.

### How to Read the Table

1. **Find the z-score**: Determine the z-score for the value you are interested in.
   
2. **Locate the row**: Find the row that corresponds to the integer and first decimal of your z-score.

3. **Locate the column**: Find the column that corresponds to the second decimal of your z-score.

4. **Read the value**: The intersection of the row and column gives the cumulative probability.

### Example

- To find the cumulative probability of a z-score of 1.63:

  - Go to the row labeled "1.6".
  - Move to the column labeled ".03".
  - The table value at the intersection is 0.9484.

This means that the probability of observing a value less than a z-score of 1.63 is 0.9484 or 94.84%.

### Graphical Explanation

The table uses the properties of the standard normal distribution, which is symmetrical around a mean of zero. The probabilities correspond to the area under the curve to the left of a given z-score.

This tool is essential for conducting hypothesis testing and constructing confidence intervals in statistical analysis.

The area of the shaded region is [   ].  
(Round to four decimal places as needed.)

**Diagram Explanation:**

The diagram shows a standard normal distribution curve. The curve is bell-shaped and symmetrical around zero. The shaded area is on the right side of the mean, extending from a z-score of 0.69 to infinity. The task is to find the area under the curve for this shaded region, representing the probability of a z-score being greater than 0.69.
