1 The results of processing with a computer on the data that have been collected in analyzing the relationship between the dependent variable (Y) with the independent variables X1 and X2 are obtained as follows: Source Level Number of Square Significance F Variation freedom Squares mean Regression 12,6102 6,3051 97,69 0,0001 Residue/Erro 17 0,7743 0,0643 Total 19 13,3847 Variable Coefficient Standard Error T stat P-value (SBI) Intercept 0.0269 0,06905 - 0,39 X1 0,7912 0,06295 12.57 0,0000 XZ 0,6048 0,07174 8.43 0,0000 Based on the results of the computer program above: 0.) Formulate the multiple regression equation! b.) Explain the meaning of each coefficient bo, b1 and b2! c.] Calculate the coefficient of determination of multiple linear regression RZy.12 and explain its meaning! d.) Calculate the correlation coefficient of multiple linear regression Ry.12 and explain its meaning c.) With 3%, test the significance of the model based on ANOVA with the following hypothesis: Ho : B = B =0 Ha : Bj # 0, j =1,2 el if the test is carried out to test the regression coemcient partially (with t test) what can you conclude for testing as follows by using a 3% : = f) Based on the model ( the equation obtained in problem a, make a forecast value for Y for X1 = 5 and X, = 3. 6) Make an interval estimate for 81 and 82, using [1 - a) = 95 % Referensi bocaan : buku J.
