Question

Could you please solve with the following question.

Prior to 1980, homeowners in Hawaii had to lease the land their homes were built on because the law
(dating back to the islands' feudal period) required land be owned only by the big estates. After 1980, a
new law instituted condemnation proceedings so that citizens could buy the land under their house.
A large Hawaiian estate wants to use regression to estimate the fair market value of its land. The data set
HAWAII contains 20 property sales in a particular neighborhood.
