Step 1 :Define the null hypothesis (H0) and the alternative hypothesis (Ha).
Step 2 :The null hypothesis (H0) is a statement of no effect, relationship, or difference. In this case, it would be that the mean Los Angeles commute time is equal to 34 minutes.
Step 3 :The alternative hypothesis (Ha) is a statement that contradicts the null hypothesis. In this case, it would be that the mean Los Angeles commute time is less than 34 minutes.
Step 4 :Final Answer: \(\boxed{\text{The null hypothesis (H0): The mean Los Angeles commute time is equal to 34 minutes.}}\)
Step 5 :Final Answer: \(\boxed{\text{The alternative hypothesis (Ha): The mean Los Angeles commute time is less than 34 minutes.}}\)
