QUESTION 3 Consider the following regression model: y=BitB2X2+BXs+B4X4+BsXstu. The sample size is N=87. Using F test, we want to test: Ho : Ba+Bs=1, B:=0 Hi : O/W. The restricted and unrestricted sum of squared errors are SSE=1161 and SSEu=903. What is the F statistics for this test.QUESTION 4 Consider the following regression model: y=BitB2X2+BXs+B4X4+BsXstu. The sample size is N=147. Using F test, we want to test: Ho : B2+Bs-Bs =0 HI : O/W. The restricted and unrestricted sum of squared errors are SSE=1190 and SSEu=822. What is the F statistics for this test
