 Question 287741: Given H0: p ≥ 80% and Ha: p < 80%, determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed.Answer by stanbon(57304)   (Show Source): You can put this solution on YOUR website!Given H0: p ≥ 80% and Ha: p < 80%, determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed. ----------------- The alternate hypotheses, Ha, ALWAYS determines the type of test. If Ha: p < # the test is left tail If Ha: p is not equal to # the test is two tail If Ha: p > # the test is right tail ----------------------------- Your Problem: Since you have Ha: p < 80%, the test is left tail. ==================================================== Cheers, Stan H.
