In a regression analysis involving 30 observations, the following estimated regression equation was obtained. ŷ = 17.6 + 3.8x, - 2.3x, + 7.6x, + 2.7x For this estimated regression equation, SST = 1,805 and SSR = 1,760. (a) At a - 0.05, test the significance of the relationship among the variables. State the null and alternative hypotheses. O Ho: One or more of the parameters is not equal to zero. H Po = P = P2 = , - P= 0 O H: One or more of the parameters is not equal to zero. H: = P2 = P3= P = 0 %3! %3! O Ho: Po = P = 2 - P3 = P =0 H: One or more of the parameters is not equal to zero. O Ho: P = 2 = P3 = Pa = 0 H: One or more of the parameters is not equal to zero.
