Answer:

The correct option is b

Step-by-step explanation:

From the question we are told that

   The average monthly  rent for one-bedroom apartment in Chattanooga has been  

         $\mu = \ 1200$

This mean that the null hypothesis is  

        $H_o : \mu = \ 1200$

Generally given from the question that it is believed that there has been a decrease in the average rental , it then mean that the  alternative hypothesis is  

         $H_a : \mu < \ 1200$
