Transcribed Image Text:**Standard Normal Cumulative Probability Table**
This table provides cumulative probabilities for negative z-values. It is used to find the probability that a standard normal random variable is less than a given z-value. The table displays a range of z-values from -3.4 to 0.0, with columns labeled 0.00 to 0.09 representing the hundredths place.
At the top right of the table, there is a diagram of a standard normal distribution curve with the shaded area representing the cumulative probability from the left up to the specified z-score.
**Table Explanation:**
- **Rows:** Each row represents a primary z-value (e.g., -3.4, -3.3, ..., -0.5).
- **Columns:** Each column, starting from 0.00 to 0.09, provides the added decimal to the main z-value from the row header. The intersection gives the cumulative probability.
**Example of Usage:**
- For a z-value of -2.5:
- Locate the row for -2.5.
- Move across to the desired column. For instance, for -2.56, use column 0.06, which corresponds to a cumulative probability of 0.0052.
This table is integral in statistics for calculating probabilities and understanding distributions within a standard normal model.
Transcribed Image Text:**Standard Normal Distribution Table**
The image illustrates a standard normal distribution table used to find probabilities associated with the standard normal distribution, often used in statistics for data analysis.
### Components of the Image:
1. **Graph of Standard Normal Distribution:**
- The bell-shaped curve depicted at the top of the image represents the standard normal distribution. The shaded area under the curve to the left of \( z_1 \) symbolizes the cumulative probability of obtaining a value less than or equal to a specific \( z \)-score.
2. **Probability Density Function (PDF):**
- The formula for calculating cumulative probabilities is given by:
\[
p(z \leq z_1) = \frac{1}{\sqrt{2\pi}} \int_{-\infty}^{z_1} e^{-\frac{1}{2}z^2} \, dz
\]
- This equation defines the probability that a value from a standard normal distribution is less than or equal to \( z_1 \).
3. **Standard Normal Distribution Table:**
- **Rows and Columns:** The table lists \( z \)-scores to two decimal places. The row headers (e.g., 0.0, 0.1, ..., 3.9) represent the whole and first decimal place of a \( z \)-score, while the column headers (0.00 to 0.09) represent the second decimal place.
- **Values:** Each cell in the table contains the cumulative probability associated with the \( z \)-score formed by combining the row and column headers. For example, to find the cumulative probability up to a \( z \)-score of 0.05, locate the row for 0.0 and column for 0.05; the cell shows 0.5199, highlighted in green.
- **Highlighted Cells:** Some cells, such as 0.05 (0.5199) and 2.10 (0.9830), are highlighted to aid identification of key probabilities.
The table provides a useful reference for determining cumulative probabilities related to the standard normal distribution, crucial for statistical analysis and hypothesis testing.
