Final Answer :
D
Explanation :
The null hypothesis (H0) is a statement of no change or no effect, so it should reflect the condition before the suspected increase, which is that the average wage is less than or equal to $21.80. The alternative hypothesis (Ha) is what the test aims to provide evidence for, which in this case is that the average wage has increased, hence it should be greater than $21.80. Therefore, the correct hypotheses are H0: μ ≤ 21.80 and Ha: μ > 21.80.
