Quizplus · Accepted Answer

The null hypothesis (H0) represents the statement that there is no change from the historical or known value, which in this case is the unemployment rate being 7.6% (or 0.076 as a proportion). The alternative hypothesis (HA) represents the claim we wish to support, which is that the current unemployment rate is different from 7.6%. Therefore, HA: p ≠ 0.076 correctly states that the current rate is not equal to 7.6%, making A the correct choice.
