As of 2012, the proportion of students who use a MacBook as their primary computer is 0.36. You believe that at your university the proportion is actually greater than 0.36. If you conduct a hypothesis test, what will the null and alternative hypotheses be?
1) HO: p = 0.36HA: p ≠ 0.36
2) HO: p ≥ 0.36HA: p < 0.36
3) HO: p > 0.36HA: p ≤ 0.36
4) HO: p < 0.36HA: p ≥ 0.36
5) HO: p ≤ 0.36HA: p > 0.36
