**Indicate the Mean and the Standard Deviation of the Distribution of Means for Each Situation**

The table presents data for calculating the mean and standard deviation of the distribution of means across several scenarios. Each scenario provides information about the population mean, variance, and sample size (N).

| Situation | Population Mean | Population Variance | Sample Size (N) |
|-----------|-----------------|---------------------|-----------------|
| (a)       | 125             | 20                  | 5               |
| (b)       | 125             | 15                  | 5               |
| (c)       | 125             | 10                  | 5               |
| (d)       | 125             | 5                   | 5               |
| (e)       | 90              | 5                   | 5               |
| (f)       | 125             | 40                  | 20              |
| (g)       | 125             | 10                  | 20              |

**Details:**

- **Population Mean**: This is the mean of the entire population from which samples are drawn.
- **Population Variance**: This is a measure of the dispersion of the population data.
- **Sample Size (N)**: This indicates the number of observations in each sample.

For each situation, use these values to calculate the mean of the distribution of means and the standard deviation of the distribution of means. The standard deviation of the distribution of means (standard error) can be calculated using the formula:

\[ \text{Standard Error} = \sqrt{\frac{\text{Population Variance}}{N}} \] 

This information is typically used in statistical analysis to understand how sample means vary from the population mean.
