A regression model involved 5 independent variables, y = Bo + 31 1 + 32x2 + B3x3 + BAX4 + B5x5 + E To test the joint significance of 12 and 14, the null hypothesis is OHo : B2 = B4 = 0 OHo : B1 = B3 = 35 = 0 OHo : B2 = 0 or Ho : B4 = 0 OHo : B2 = 0 or B4 = 0A regression model involved 5 independent variables, for example, y = Bo + BIX1 + 32x2 + B3x3 + B4x4 + 3525 + E MSR To test the joint significance of 12 and 14, the F-statistic = MSE O True C FalseA regression model involved 5 independent variables, for example, y = Bo + BIX1 + B2X2 + B3x3 + BAX4 + 35x5 + E To test the joint significance of 12 and 14, which of the following models should be used to obtained SS Erestricted? Oy = Bo+ B121 + B2 2 + B323 + BAX4 + B525 + E Oy = Bot B2ac2 + BAX4 + E Oy = Bot B121 + B323 + 3525 + E Not enough information is provided to answer this
