Consider the data from Exercise 11-12 on y = chloride
Chapter 11, Problem 38E(choose chapter or problem)
Consider the data from Exercise 11-12 on \(y=\text { chloride concentration in surface streams }\) and \(x=\text { roadway area }\).
Test the hypothesis \(H_0\ :\ \beta_1=0\) versus \(H_1\ :\ \beta_1\ne0\) using the analysis of variance procedure with \(\alpha=0.01\).Find the P-value for the test in part (a).Estimate the standard errors of \(\hat{\beta_{1}}\) and \(\hat{\beta_{0}}\).Test \(H_0\ :\ \beta_1=0\) versus \(H_1\ :\ \beta_0\ne0\) using \(\alpha=0.01\). What con-clusions can you draw? Does it seem that the model might be a better fit to the data if the intercept were removed?Equation Transcription:
