I need help finding the answers that go into the yellow highlighted boxes :) Thank you so much!!

### Calculating the Z-Value for Confidence Intervals

To determine the z-value for the following confidence intervals, use the `Norm.S.Inv` function. 

Here's the table:

| **S.No** | **Confidence Interval** | **Z-Value** |
|----------|-------------------------|-------------|
| 2        | 99% Confidence Interval  |{Textbox with yellow highlight}|
| 2        | 95% Confidence Interval  |{Textbox with yellow highlight}|
| 2        | 90% Confidence Interval  |{Textbox with yellow highlight}|

#### Instructions:
- **S.No**: The serial number for reference.
- **Confidence Interval**: Specifies the confidence level for which the z-value is calculated.
- **Z-Value**: This is the calculated z-value for the given confidence interval, to be filled in the highlighted yellow text boxes.

> **Note**: Use the `Norm.S.Inv` function to calculate the z-values.

Understanding confidence intervals and z-values is essential in statistics for hypothesis testing and estimating population parameters. Using the correct function, such as `Norm.S.Inv`, ensures accurate computations for various confidence levels.
