Civil engineers at West Virginia University have developed a 3D model to predict the response of jointed

Question:

Civil engineers at West Virginia University have developed a 3D model to predict the response of jointed concrete pavement to temperature variations. (The International Journal of Pavement Engineering, Sept. 2004.) To validate the model, model predictions were compared to field measurements on key concrete stress variables taken at a newly constructed highway. One variable measured was slab top transverse strain (i.e., change in length per unit length per unit time) at a distance of 1 meter from the longitudinal joint. The 5-hour changes (8:20 P.M. to 1:20 A.M.) in slab top transverse strain for 6 days are listed in the next table. Is there a significant difference between the mean daily transverse strain changes from field measurements and the 3D model? Test using α = .05.
