Question 3 of 12
A test statistic is found to have a P-value of 015. Which of the following statements are true?
I This finding is significant at the 05 level of significance
II. This finding is significant at the 01 level of significance.
III. The probability of getting a test statistic as extreme (or more extreme) as this one by chance alone is 015.
A. I and III only
B. I only
C. II only
D. Ill only
E. I and II only
A. I and III only
Explanation: The P-value of 0.15 means that there is a 15% chance of obtaining a test statistic as extreme (or more extreme) as the one observed by chance alone. This finding is not significant at the 0.05 level of significance, but it would be considered significant at the 0.10 level of significance.
