Rocket Experiments Narrative
An engineer was investigating the relationship between the thrust of an experimental rocket (y), the percent composition of a secret chemical in the fuel (x₁), and the internal temperature of a chamber of the rocket (x₂). The engineer starts by fitting a quadratic model, but he believes that the full quadratic model is too complex and can be reduced by including only the linear terms and the interaction term.
-Refer to Chemical Analysis Narrative. Use the statistical software output below to test whether the reduced model is adequate at the 0.05 level of significance.
