Math Problem Statement

Nationwide, there is a 0.34 probability of randomly selecting student taking an evening class (no daytime classes).

In order to see if the probability of finding an evening student at Tucson College is smaller than this, the result from a random sample of 198 students there was that 0.21 of them are taking an evening class (no daytime classes).

Select all of the alternate hypotheses that are appropriate for this test.

   Ha:x¯>0.21

   Ha:p^<0.21

   Ha:p<0.21

   Ha:p^≠0.21

   Ha:μ≠0.21

   Ha:x¯<0.21

   Ha:x¯≠0.21

   Ha:p^>0.21

   Ha:p>0.21

   Ha:p≠0.21

   Ha:μ>0.21

   Ha:μ<0.21

   None of These do not include tops just the answer
