Hypothesis Testing
I am clueless on this, any help or advice would be appreciated.
Thanks,
To conduct a onesided hypothesis test of the claim that houses located on corner lots (cornerlot houses) have higher average selling prices than those located on noncorner lots, the following alternative hypothesis should be used:
 The average selling price of a cornerlot house is higher than it is commonly believed to be.
 The average selling price of a cornerlot house is the same as the average selling price of a house not located on a corner lot.
 The average selling price of a cornerlot house is higher than the average selling price of a house not located on a corner lot.
 The average selling price of a cornerlot house is higher than the average selling price of all houses.

We'd have $\displaystyle H_o $ : The average selling price of a cornerlot house is the same as the average selling price of a house not located on a corner lot
And $\displaystyle H_1 $ :The average selling price of a cornerlot house is higher than the average selling price of a house not located on a corner lot
So the latter is the alternative hypothesis.
