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 whether the test is a left-tail test, a right-tail test, or a two-tailed test.

H0:p1=p2H0:p1=p2 vs Ha:p1<p2Ha:p1<p2
Sample: p1^=0.3p1^=0.3, n=20n=20, p^2=0.167p^2=0.167, n=12n=12
Randomization statistic: p^1−p^2p^1-p^2



(a) Indicate where the randomization distribution will be centered. 

 

(b) Indicate whether the test is a left-tail test, a right-tail test, or a two-tailed test.
