WebAug 8, 2024 · The results of the test are printed, including the t-statistic, the degrees of freedom, the critical value, and the p-value. We can see that both the t-statistic and p-value match the outputs of the SciPy function. The test appears to be implemented correctly. The t-statistic and the p-value are then used to interpret the results of the test.
