## Description
This application performs simple random sampling on a specified population. Enter the population size,
sample size, and an optional random seed in the sidebar and press 'Generate Sample' to see the results.
## Instructions
- **Population Size**: Total number of items in your population.
- **Sample Size**: Number of items to randomly select from your population.
- **Random Seed**: A seed value to ensure reproducibility of your sample.
