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 1.25 1.71 2.07 find the value of r2. (round your answer to three decimal places.) r2 =

92.616%

Step-by-step explanation:

Given is the data of x and y where

x = current density (mA/cm2) and

y = rate of deposition (µm/min)

to find out whether there is linear relationship between x and y

xy

200.14

401.25

601.71

802.07

r0.962364513

r^20.926145457

Since r is very near to 1, we find that there is a strong positive correlation and hence linearity can be assumed

r square the coefficient of determination is 0.9261 which is 92.616%

this is the measure which accounts for variation in x due to y and or variation in y due to x.

450 is the final answer! : )
