You may need to use the appropriate technology to answer this question. A data set consisting of 7 observations of a dependent variable y and two independent variables x, and x₂ was used in a regression analysis. Using x, as the only independent variable, the following function is provided. ý = 0.405 + 1.331x, The SSE for the above model is 36.735. Using both x, and x, as independent variables yields the following function. ŷ = 0.801 + 0.493x₁ -0.479x2 The SSE for this function is 1.055. Use an F test and determin if x₂ contributes significantly to the model. Let a = 0.10. State the null and alternative hypotheses. O Ho: One or more of the parameters is not equal to zero. H₂: B₁ = B₂ = 0 Ho: B₂ = 0 H: B₂0 |O Ho: B1 = Bz = 0 H: One or more of the parameters is not equal to zero. O Ho: Bo = B1 = B2 = 0 H: One or more of the parameters is not equal to zero. O Ho: B₂0 H₂: B₂ = 0 Find the value of the test statistic. (Round your answer to two decimal places.) 169.10 x
