Question
For a hypothesis test of H0:p1 p2 = 0 against the alternative Ha:p1 p2 0, the test statistic is found to be 3.31. Which of the following statements can you make about this finding? (4 points)
The result is significant at both = 0.05 and = 0.01.
The result is significant at = 0.05 but not at = 0.01.
The result is significant at = 0.01 but not at = 0.05.
The result is not significant at either = 0.05 or = 0.01.
The result is inconclusive because we don't know the value of p.
The result is significant at both = 0.05 and = 0.01.
The result is significant at = 0.05 but not at = 0.01.
The result is significant at = 0.01 but not at = 0.05.
The result is not significant at either = 0.05 or = 0.01.
The result is inconclusive because we don't know the value of p.
Explanation / Answer
Two tailed p - value corresponding to z = 3.31 is:
p - Value = 2*P(z > 3.31) = 2*0.0005 = 0.0010
Hence,
The result is significant at both = 0.05 and = 0.01.
Option A is correct.
