The image shows a frequency distribution table regarding points scored by teams in the National Football League during a season, as well as some exercises asking to perform calculations and create visualizations. Here's the breakdown of the table:

- **Group (Puntos anotados por equipo):**
  - 0-3
  - 4-10
  - 11-17
  - 18-24
  - 25-31
  - 32-38
  - 39-45
  - 46-52

- **Frecuencia (Frequency):**
  - 27
  - 66
  - 91
  - 70
  - 57
  - 34
  - 16
  - 3

### The exercises are:

1. **Graph the relative frequency distribution.**
2. **Calculate the mean and mode.**
3. **Calculate the variance and standard deviation.**

Would you like me to walk through the steps for any of these calculations, or provide the graph first?

The table represents the points scored by teams in the National Football League during a season, grouped by ranges with corresponding frequencies. The user is asked to graph the relative frequency distribution, calculate the mean, mode, variance, and standard deviation.

This problem explores how to calculate the mean, mode, variance, and standard deviation for grouped frequency data. Using an example from a National Football League season, you'll learn the steps to summarize data with essential statistics.
