- The graph shows the distribution of worm lengths in a sample.
- The x-axis represents the length of worms in centimeters, ranging from 4.0 cm to 9.0 cm.
- The y-axis represents the number of worms, ranging from 0 to 7.
- The data forms a bell-shaped curve, indicating a normal distribution centered around 6.5 cm to 7.0 cm.
- The highest frequency (6 worms) occurs at approximately 6.8 cm.
- Fewer worms are found at the extremes: 1 worm at 5.0 cm and 1 worm at 8.5 cm.
- The total number of worms sampled can be calculated by summing the y-values at each x-value: 0 + 1 + 2 + 4 + 6 + 4 + 2 + 1 + 0 = 20 worms.
- This distribution suggests that most worms are close to the average length, with fewer very short or very long worms.
