Since the obtained result has a probability of 0.01, which is less than the alpha level of 0.05, it indicates statistical significance. However, because the result is in the opposite direction to that predicted by the alternative hypothesis (H1), we cannot accept H1. Instead, we retain the null hypothesis (H0) because the evidence does not support H1 as expected.
