The Following Table Presents Measurements of the Tensile Strength (In $m$

Essay

The following table presents measurements of the tensile strength (in kilopascals) asphalt-rubber concrete beams for three levels of binder content and three levels o rubber content.


i). Can you reject the hypothesis of no interactions?
ii). Can the mean effect of the binder content be interpreted? If so, interpret the $m$ effect.
Use the $\alpha = 0.01$ level of significance.
iii). Can the mean effect of the rubber content be interpreted? If so, interpret the $\mathrm { m }$ effect. Use the $\alpha = 0.01$ level of significance.
