Suppose Peter has $800,000 to spend on a house and “other goods” (denominated in dollars). The price of 1 square foot of housing is $300, and Peter chooses to purchase a house of 2,000 square feet in size. Assume that houses do not differ in quality: their price is solely determined by their size. Also, assume throughout that Peter spends money on housing solely for its consumption value, not as part of his investment strategy, and that Peter has well-behaved,...

Suppose the following data were collected relating the selling
price of a house to square footage and whether or not the house is
made out of wood. Use statistical software to find the regression
equation. Is there enough evidence to support the claim that on
average wood houses are more expensive than other types of houses
at the 0.01 level of significance? If yes, type the regression
equation in the spaces provided with answers rounded to two decimal
places. Else,...
