How probable is it?
binom_draws = np.random.binomial(12, 0.5, size=100000)
np.sum(binom_draws <= 1) / 100000
0.0033600000000000001
Your tasks
- Investigate improvement of individual swimmers moving from low- to high-numbered lanes in 50 m events
- Compute the size of the effect
- Test the hypothesis that on average there is no difference between low- and high-numbered lanes
