An article presented data on compressive strength x and intrinsic permeability y of various concrete mixes and cures. Summary quantities are n = 14, Xy; = 572, Xy} = 23530, X 43, Xx} = 157.42, and Xxiy; = 1697.80. Assume that the two variables are related according to the simple linear regression model. = Yi = X; Round your answers to 3 decimal places. (a) Test for significance of regression using a = 0.05. (b) Estimate 62. (c) In this model, what is the standard error of the intercept? i What is the standard error of the slope?
