State the null and alternative hypotheses for this test. Ho: : :: 44. :: eTextbook and Media :: :: μ μ4 :: 2 vs Ha: ::H₂ :: p :: P₁ :: p :: P₁ :: P₂ :: P₂ #r :: # I :: p :: T :: I₁ (b) For the test in part (a), the evidence from the sample was not strong enough to support the alternative hypothesis.
