1. ## Hypothesis Testing

I am clueless on this, any help or advice would be appreciated.

Thanks,

To conduct a one-sided hypothesis test of the claim that houses located on corner lots (corner-lot houses) have higher average selling prices than those located on non-corner lots, the following alternative hypothesis should be used:

• The average selling price of a corner-lot house is higher than it is commonly believed to be.
• The average selling price of a corner-lot house is the same as the average selling price of a house not located on a corner lot.
• The average selling price of a corner-lot house is higher than the average selling price of a house not located on a corner lot.
• The average selling price of a corner-lot house is higher than the average selling price of all houses.

2. We'd have $H_o$ : The average selling price of a corner-lot house is the same as the average selling price of a house not located on a corner lot

And $H_1$ :The average selling price of a corner-lot house is higher than the average selling price of a house not located on a corner lot

So the latter is the alternative hypothesis.
