Short Answer

When a regression model was developed relating sales (y) of a company to its product's price (x₁), the SSE was determined to be 495. A second regression model relating sales (y) to product's price (x₁) and competitor's product's price (x₂) resulted in an SSE of 396. At α = .05, determine if the competitor's product's price contributed significantly to the model. The sample size for both models was 33.
