1. Identify the largest coefficient. What is its value and what is the interpretation of this number? 

a. 4.17; This is the amount in thousands that the selling price of a new house will increase.  

b. 4.17; This shows how much the selling price correlates with the age of the house  

c. 4.411; The older the house, the higher the selling price by this amount in thousands.  

d. 4.411; For each additional bathroom the selling price of the house increase by 4.41 hundred thousand dollars.  

2. Which of the three variables has the second best P-value and what is this P-value? 

a. Age has second best P-value; P-value = 0.018  

b. The higher the P-value, the better; so a P-value = 0.043 is very good.  

c. #Rooms has second best P-value; P-value = 0.043  

d. All P-values are poor since they are all below 5%.  

3. Using this second table predict the selling price of a house that is 10 years old, has 2 bathrooms and 3 rooms.

a. 10.5 hundred thousands  

b. 12.93 hundred thousands  

c. 9.06 hundred thousands  

d. 13.2 hundred thousands  

4. What is the Y intercept and its interpretation?

a. 1.267;This number is used to predict the selling price of the house based on the variables.  

b. 0.837;This number shows how much the house selling price correlates with the other variables.  

c. -1.437; It has no meaningful interpretation in this case.  

d. -1.43; This is how much the new house price will decrease.
