Using the HomesForSale data set from Lock5With R, fit a linear model for Price of a house given Size and Beds. To access the package using R studio, install the package "Lock5WithR". Then, do library(HomesForSale)

a)Use the bootstrap method to perform a hypothesis test about whether the number of beds is needed in a model of price that includes both size and beds. Provide your code and explain your steps for solving the previous problem.

b)Using a residuals vs fitted plot explain why the bootstrap method is needed for this model.

c)Using a residuals vs fitted plot explain why the bootstrap method is not needed if the response is log price instead of price.
