A tire manufacturer claims that the mean mileage of its competitor’s tires is less than $40,000$ miles. You are asked to conduct a hypothesis test to evaluate this claim. How would you state the null and alternative hypotheses if you were representing the competitor and wanted to reject the claim?

$\{\begin{array}{c}{H}_0:\mu <40,000\\ H_a:\mu \ge 40,000\end{array}$

$\{\begin{array}{c}{H}_0:\mu =40,000\\ H_a:\mu \ne 40,000\end{array}$

$\{\begin{array}{c}{H}_0:\mu \le 40,000\\ H_a:\mu >40,000\end{array}$
