I need help with this question 5

Let \( z \) be a standard normal random variable with mean \( \mu = 0 \) and standard deviation \( \sigma = 1 \). Use Table 3 in Appendix I to find the probability. (Round your answer to four decimal places.)

\[ P(-2.58 < z < 2.58) = \] [Input box]

There is an orange button labeled "USE SALT" above the input box.

### Understanding Standard Normal Distributions

**Problem Statement:**

Consider a standard normal random variable \( z \) with the following characteristics:
- **Mean (\(\mu\))**: 0
- **Standard Deviation (\(\sigma\))**: 1

To determine the probability \( P(z < 1.645) \), refer to **Table 3 in Appendix I**. Ensure to round your answer to four decimal places.

**Instructions:**

1. **Use the SALT Tool**:
   - There is an option labeled "USE SALT" which may provide additional computational support.

2. **Calculating the Probability**:
   - Use the standard normal distribution table to find the area under the curve to the left of \( z = 1.645 \).

3. **Result Calculation**:
   - Input the probability value in the provided space.

4. **Rounding**:
   - The final answer should be rounded to four decimal places for precision.

This exercise helps in understanding how to utilize standard normal distribution tables and tools for calculating probabilities related to normally distributed variables.
