An experiment was carried out to compare electrical resistivity for six different low-permeability concrete bridge deck mixtures. There were 26 measurements on concrete cylinders for each mixture; these were obtained 28 days after casting.

An article in Concrete Research ["Near Surface Characteristics of Concrete: Intrinsic Permeability" (1989, Vol.41) ] presented data on compressive strength x and intrinsic permeability y of various concrete mixes and cures. Summary quantities are n=14, ∑yi=572, ∑yi^2=23,530, ∑xi=43, ∑xi^2=157.42, and ∑xi yi=1697.80 . Assume that the two variables are related according to the simple linear regression model. (a) Calculate the least squares estimates of the slope and intercept. Estimate σ^2. Graph

SOLVED:An experiment was carried out to compare electrical resistivity for six different low-permeability concrete bridge deck mixtures. There were 26 measurements on concrete cylinders for each mixture; these were obtained 28 days after casting. The entries in the accompanying ANOVA table are based on information in the article "In-Place Resistivity of Bridge Deck Concrete Mixtures" (ACl Materials J., 2009: 114-122). Fill in the remaining entries and test appropriate hypotheses.

SOLVED:Consider the data from Exercise 11-1 on x= compressive strength and y= intrinsic permeability of concrete. (a) Test for significance of regression using α-0.05 . Find the P -value for this test. Can you conclude that the model specifies a useful linear relationship between these two variables? (b) Estimate σ^2 and the standard deviation of β̂1. (c) What is the standard error of the intercept in this model?
