QUESTION 1 Consider the following regression model: y=BitB2X2+BsXs+B4X4+BsXstu. The sample size is N=105. Using F test, we want to test: Ho : B2+Bs=1, B2=0, B4=4 Hi : O/W. What is the number of restrictions in the null hypothesis. Oa. 4 Ob. 1 Oc. 3 Od. 2QUESTION 2 Consider the following regression model: y=BitBzX2+BXs+B4X4+BsXstu. The sample size is N=105. Using F test, we want to test: Ho : Bz=0, B:=0 H1 : O/W. The restricted and unrestricted sum of squared errors are SSEr=1200 and SSEu=1000. What is the F statistics for this test.
