If a one-tailed test gives a p-value of 0.02, what would the corresponding two-tailed p-value be for the same symmetric statistic?
Correct answer B. 0.04
Explanation
For a symmetric distribution, the two-tailed p-value counts equally extreme results in both tails, so it is double the one-tailed value: 2 × 0.02 = 0.04.
