Since 285.775>4.74, we ignore the null hypothesis and conclude that Y = b 0 or Y = b 0 + b 1 X 1 + b 2 X 2. Web8 feb. 2024 · F denotes the F -test for the null hypothesis. Significance F denotes the P -value of F. Then you will also get the variable’s coefficients, significance value, etc in a table. Then you will get a final table below the coefficient table which contains the residual value for each entry.
