A Data Set Consisting of 7 Observations of a Dependent

question 13

Short Answer

A data set consisting of 7 observations of a dependent variable y and two independent variables x₁ and x₂ was used in a regression analysis. Using x₁ as the only independent variable, the following function is provided. = .408 + 1.338x₁
The SSE for the above model is 39.535.
Using both x₁ and x₂ as independent variables yields the following function. = .805 + .498x₁ - .477x₂
The SSE for this function is 1.015.
Use an F test and determine if x₂ contributes significantly to the model. Let α = .10.
