Question: The accompanying data on x = current density (mAycm2) and y = rate of deposition smmymin d appeared in the article Plating of 60/40 Tin/Lead

The accompanying data on x = current density (mAycm2) and y = rate of deposition smmymin d appeared in the article "Plating of 60/40 Tin/Lead Solder for Head Termination Metallurgy" (Plating and Surface Finishing, Jan. 1997: 38-40). Do you agree with the claim by the article's author that "a linear relationship was obtained from the tin-lead rate of deposition as a function of current density"? Explain your reasoning.
