The predicted value of the house price when SqFt is 2275 and it is made of brick is
Price = 111974 + 35.619*2275 + 5683 *1 = $ 198689.
Q 31) The p-value for the test of slope corresponding to the independent variable SqFt is 0.000 and less than 0.01. Hence, we can conclude that the coefficient of SqFt is significant at the 0.01 level of significance.
Ans: Yes.
