A probability value (p-value) from a t-test that is less than the alpha level (typically set at 0.05) suggests that the observed data are unlikely under the null hypothesis (H₀). This leads to rejecting the null hypothesis, indicating that the observed effect is statistically significant and not likely due to random chance.
