We had seen that if there are r rows and c columns, then the degrres of freedom would be (r-1)*(c-1). As per this, in Question 4.21 (b), the degrees of frredom would be 2. In the solution, it is given as 4 i.e., number of cells - number of estimated parameters - 1. Are these two different methods of testing the hypothesis? Please let me know if my understanding is wrong.
