If a test is significant at α= 0.05, it means the p-value is less than 0.05. Therefore, the test would also be significant at any higher alpha level (e.g., α= 0.10) because the p-value would still be less than the alpha level, indicating statistical significance. However, it might not be significant at a lower alpha level (e.g., α= 0.01) because the p-value could be higher than this more stringent criterion.
