## Cumulative Standardized Normal Distribution Tables

### Introduction
Given a standardized normal distribution (with a mean of 0 and a standard deviation of 1), use the cumulative standardized normal distribution tables to complete probability calculations.

### Navigation
- **Page 1:** Values from Z = -3.0 to Z = 0.0
- **Page 2:** Values from Z = 0.0 to Z = 3.0

### Understanding the Tables
Each table provides cumulative probabilities for different Z-scores. A Z-score represents the number of standard deviations a data point is from the mean.

### Page 1 Details
- The leftmost column contains Z-scores ranging from -3.0 to -0.1.
- The top row indicates the additional decimal place for each Z-score from 0.00 to 0.09.
- The intersection of a Z-score row and a column gives the cumulative probability for that Z-score.

#### Example
- For Z = -2.3, the probability is found in the row starting with -2.3 and the column labeled 0.00, which is 0.0107.

### Page 2 Details
- The leftmost column contains Z-scores ranging from 0.0 to 3.0.
- The top row indicates the additional decimal place for each Z-score from 0.00 to 0.09.
- The intersection of a Z-score row and a column gives the cumulative probability for that Z-score.

#### Example
- For Z = 1.5, the probability is found in the row starting with 1.5 and the column labeled 0.09, which is 0.9332.

### Application
These tables are essential for statistical analyses involving the normal distribution, allowing for quick determination of probabilities and critical values.

#### Usage in Problems
1. Identify the Z-score for which you need the probability.
2. Find the Z-score in the left column and move across to the specified decimal column.
3. Use the intersection value as the probability.

### Conclusion
These tables simplify the process of finding cumulative probabilities for Z-scores, crucial for tasks in statistics and data analysis.

### Additional Options
Options to **Print** or mark as **Done** are available for output or submission confirmation.

For further assistance or questions on interpreting these values, consult with supplemental statistical resources or reach out to your educational instructor.
