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

Essay

The following table presents measurements of the tensile strength (in kilopascals) of asphalt-rubber concrete beams for three levels of binder content and three levels of 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 $m$ effect. Use the $\alpha = 0.01$ level of significance
