  The population mean is  \mu =  31 \  miles / gallon

Generally

   The null hypothesis is that the company's  new sedan, the Libra, will have an average of   \mu =  31 \  miles / gallon

This mathematically  represented as

The null hypothesis   H_o :  \mu =  31

   The alternative hypothesis is that the company's  new sedan, the Libra, will have an average better than   \mu =  31 \  miles / gallon

This mathematically  represented as

     The alternative hypothesis H_a :  \mu >  31
