(Questiоns 21 tо 22) Dаtа in hоuse.xls аre from a sample of 30 single-family homes located in Ala county, 30 miles east of New York City. Variables included are house price in $1000, the land area of the property in acres (Lotsize), interior size of the house (Squarefootage), number of years since built(Age), number of rooms(Rooms), number of bathrooms(Baths), and number of cars that can be parked in the garage (Garage). A realtor would like to develop the most appropriate multiple regression model to predict the house price considering the above factors. Write down the answers to the following five questions in a Word document, take a screenshot of your R code and output and put it in the same Word document, and upload it. (Round all the coefficients to two decimal places) Is there collinearity among the factors that the realtor is considering? Should any factor be removed? ( 2 points) Build a multiple linear regression model based on the factors you choose in part I, and state the regression equation. (2 points) Perform the corresponding tests to identify the significant factors at the significance level of 0.05. (3 points) What are the r2 and adjusted r2 values for the regression model built in Part III? Interpret the meanings. Which one should be used? (2 points)
