Consider the data from Exercise 11-3 on x = compressive
Chapter 11, Problem 29E(choose chapter or problem)
Consider the data from Exercise 11-3 on \(x=\text { compressive strength }\) and \(y=\text { intrinsic permeability of concrete }\).
Test for significance of regression using \(\alpha=0.05\). Find the P-value for this test. Can you conclude that the model specifies a useful linear relationship between these two variables?Estimate \(\sigma^{2}\) and the standard deviation of \(\hat{\beta_{1}}\)..What is the standard error of the intercept in this model?
