Bart believes that mice exposed to radio waves will become extra strong (maybe he's been reading too much Radioactive Man). He decides to perform this experiment by placing 10 mice near a radio for 5 hours. He compared these 10 mice to another 10 mice that had not been exposed. His test consisted of a heavy block of wood that blocked the mouse food. he found that 8 out of 10 of the radio waved mice were able to push the block away. 7 out of 10 of the other mice were able to do the same

Bart's experiment seeks to test whether exposure to radio waves affects the strength of mice. He compared two groups of mice: one group exposed to radio waves for 5 hours and another group that was not exposed. The results showed that 8 out of 10 mice in the radio wave group were able to push away a heavy block of wood, while 7 out of 10 mice in the control group were able to do the same.

Here's how we can break down the results:

- **Radio Wave Group:**
- Mice that pushed the block: 8
- Mice that did not push the block: 2
- Success rate: \( \frac{8}{10} = 80\% \)

- **Control Group (No Exposure):**
- Mice that pushed the block: 7
- Mice that did not push the block: 3
- Success rate: \( \frac{7}{10} = 70\% \)

### Observations:
1. The radio wave group had a higher success rate (80%) compared to the control group (70%).
2. To assess whether the difference in success rates is statistically significant, Bart could perform a statistical test (such as a chi-square test or Fisher's exact test) to determine if the observed difference is likely due to chance.

### Considerations:
- **Sample Size:** Bart's experiment involves a small sample size (10 mice per group), which may limit the generalizability of the results.
- **Replication:** The experiment should be repeated with larger sample sizes and possibly controlled conditions to strengthen the findings.
- **Variables:** Other factors, such as the mice's age, health, and genetic background, should also be considered, as they may influence strength independent of radio wave exposure.
- **Mechanism:** If the experiment shows consistent results, further studies could investigate the biological mechanisms by which radio waves might enhance strength.

In conclusion, while Bart's initial findings suggest a potential effect of radio waves on mice strength, further testing and controls are needed to validate the results.
