Question
  1. Five scenarios are presented below, labeled (i) through (v).  For each scenario, you are given hypotheses, along with the resulting test statistic.  

 

  1. Ho: p = 0.3 vs. Ha: p > 0.3, z = 1.7
  2. Ho: p = 0.75 vs. Ha: p < 0.75, z = -1.7
  3. Ho: p = 0.25 vs. Ha: p ≠ 0.25, z = 1.7
  4. Ho: p = 0.5 vs. Ha: p ≠ 0.5, z = -2.7
  5. Ho: p = 0.5 vs. Ha: p > 0.5, z = 2.7
