Question

1. A result is significant at the 0.01 level. Explain why it must also be significant at the 0.05 level.
2. Why is it important to report the P-value or the test statistic when presenting the results of a hypothesis test?

Answer 1

1: The P-value is less than 0.01, from which it is less than 0.05, thus the result is significant at the 0.05 level.

2: The P-value is important because it can be used to decide if the result is significant for any level.
