Example

clouds = pd.read_csv('https://raw.githubusercontent.com/jillxoreilly/StatsCourseBook_2025/main/data/cloudSeeding.csv')

test = HypothesisTest(clouds)
test.measuring_column('rainfall').query_on_column('status').set_datapoints('Unseeded', 'Seeded')

print(test.using_permutation().exec())

This yields:

H0: The difference in mean rainfall between group Unseeded and group Seeded is zero.
H1: The difference in mean rainfall between group Unseeded and group Seeded is two-sided than zero.
This is a two-sided (non-directional) alternative hypothesis.

Test statistic: difference in mean rainfall between group Unseeded and group Seeded (-277)
Alpha: 0.05

P-value: 0.052 (after 10000 permutations)

0.052 > 0.05.
There is insufficient evidence to reject the null hypothesis.
