Question

Quizplus · Accepted Answer

The p-value of .0808 suggests that there is an 8.08% chance of observing a sample with 16 or more dissatisfied employees out of 25 if the true proportion of dissatisfied employees in the company does not exceed half. This relatively low p-value indicates evidence against the null hypothesis (that half or fewer are dissatisfied), supporting the consideration for changing the health plan.
