Exploring sample size
Now we'll explore the effect of sample size on the results of statistical tests. Here, we'll be comparing the Weight of American Athletics and Swimming competitors in the athletes dataset. The boxplots show the difference between these two groups.
Using a defined seed and varying sample sizes, you will perform t-tests comparing the Weight of samples from both Sports. random, scipy.stats, and pandas have been loaded for you as random, stats, and pd.

Hands-on interactive exercise
Have a go at this exercise by completing this sample code.
# Create subset with defined random seed and perform t-test
subset = athletes.sample(n=____, random_state= 1007)
print(stats.ttest_ind(____[____.Sport == "Athletics"].Weight, ____ ))
