Scientific Computing
Builds on these lessons
Current Task
Objective
ttest_ind() compares the means of two independent samples, returning a p-value — how likely the difference is due to chance.
Task: compare old vs. new login times with a t-test and print the p-value.

from scipy.stats import ttest_ind
old_login_times = [4.2, 4.5, 4.1, 4.8]
new_login_times = [3.1, 3.4, 3.0, 3.3]
result = ttest_ind(old_login_times, new_login_times)
print(result.pvalue)
