The accompanying data on x = current density (ma/cm2) and y = rate of deposition (µm/min) appeared in an article. 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"? x 20 40 60 80 y 0.14 1.20 1.76 2.22 find the value of r2. (round your answer to three decimal places.)
