The null and alternative hypotheses for a test are given, as well as some information about the actual sample and the statistic that is computed for each randomization sample. Indicate where the randomization distribution will be centered.

Ho: p1 = p2 vs. Ha: p1>p2

Sample: p̂1 = 0.3, n=20, p̂2 = 0.467 n=12
Randomization statistic p̂1 - p̂2

P.S. The answer is not -0.167
