An article presented data on compressive strength x and intrinsic permeability y of various concrete mixes and cures. summary quantities are n = 14, σ ri = 572 , σ y? = 23530, σ x, = 43 , σ×7-15742 = 157.42 and xi , = 16g/.80 . assume that the two variables are related according to the simple linear regression model. round your answers to 3 decimal places. (a) test for significance of regression using α=0.05 2 (b) estimate σ (c) in this model, what is the standard error of the intercept? what is the standard error of the slope?
