Question 9

More than $74 \%$ of workers indicate that they are dissatisfied with their job. Express the null and alternative hypotheses in symbolic form for this claim (enter as a percentage).
\[
H_{0}: p
\]
\[
H_{1}: p
\]

Step 1 ：The null hypothesis (H0) is a statement of no effect or no difference. It is the hypothesis that the researcher is trying to disprove. In this case, the null hypothesis would be that the proportion of workers who are dissatisfied with their job is equal to 74%.

Step 2 ：The alternative hypothesis (H1) is a statement that contradicts the null hypothesis. It is the hypothesis that the researcher believes to be true. In this case, the alternative hypothesis would be that the proportion of workers who are dissatisfied with their job is more than 74%.

Step 3 ：Final Answer: \n \(H_{0}: p = 0.74\) \n \(H_{1}: p > 0.74\)
