You are given the following information about y and x: y Dependent Variable x Independent Variable 12 4 3 6 7 2 6 4 Furthermore, the following sums were calculated: SST = 42 SSE = 34 Can someone tell me why n=3 and k=1 for this above? I thought k would be = 4 because it is the # of X variables. Pretty confused. Thank you
