Consider the following data for a dependent variable y and two independent variables, x ] and x2. X 1 X2 y 30 12 96 47 10 108 25 17 112 51 16 178 40 5 94 51 19 175 74 7 170 36 12 117 59 13 142 76 16 210 The estimated regression equation for these data is y = -16.65 + 1.99x1 + 4.71x2. Here, SST = 14,861.6, SSR = 13,748.5, sb, = 0.2452, and sb, = 0.9410. (a) Test for a significant relationship among X1, X2, and y. Use a = 0.05. State the null and alternative hypotheses. O HO: B1 > B2 Ha : B1 = P2 O Ho: B1 + 0 and $2 = 0 Ha: $1 = 0 and B2 # 0 O Ho: B1 # 0 and $2 # 0 Ha: One or more of the parameters is equal to zero. O HO: B1
