# Standard Normal Tables

## Standard Normal Table (Page 1)

### Description:
The table provides the cumulative probabilities for a standard normal distribution. It shows the area under the standard normal curve to the left of a given z-score.

### Graph Explanation:
- **Graph**: A bell-shaped standard normal distribution curve is displayed, illustrating cumulative probability.
- **Legend**: Indicates how to interpret cumulative probability up to a certain z-score.

### Table:
