Using information below (partial F test), explain how to find numerator and denominator degrees of freedom. You do not need to perform the partial F test, only explain how to find numerator and denominator degrees of freedom.

A data set consisting of 22 observations of a dependent variable y and four independent variables x1, X2, x3 and x4 was used in a regression analysis. Using only x 1 as the independent variable, the following prediction formula was generated: y = 0.408 + 1.338(x1), with SSE = 36.625 Using all the independent variables yielded this equation: y = 0.805 + 0.498(x1) - 0.477(x2) + 1.204(x3) - 0.055(x4), with SSE = 21.250 Follow along with the steps below to conduct a partial F test to determine if x2, X3 and x4 simultaneously contribute significantly to the model. Let a = 0.05
