An article in Concrete Research ("Near Surface Characteristics of Concrete: Intrinsic Permeability," Vol. 41, 1989), presented data on compressive strength x and intrinsic permeability y of various concrete mixes and cures. Summary quantities are n = 14, Σv = 572, Σ ν = 23,530, Σx = 43, Σ x = 157.42, and Exy = 1697.80. Assume that the two variables are related according to the simple linear regression model.
