Housing units

Variables often have units: age is in years, price is in dollars or euros or renminbi, etc. In the Houses_for_sale data, the unit for price is dollars, for land_value it's also dollars, and for living_area it's square feet. fireplaces is a pure number, without units.

In this exercise, you'll find the units of effect sizes. For quantitative explanatory variables, effect sizes always have the unit of the response variable divided by the unit of the explanatory variable.

Using the Houses_for_sale data, build an lm() model of house price versus living_area, land_value, and fireplaces (all together).

Which of these statements is true?
