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 thearticle's author that "a linear relationship was obtained from thetin-lead rate of deposition as a function of current density"?
x | 20 | 40 | 60 | 80 |
y | 0.29 | 1.10 | 1.76 | 2.07 |
Find the value of r2. (Round your answer tothree decimal places.)
r2 =
Explain your reasoning.
The very high value of r2 denies theauthor's claim.
The very low value of r2 confirms theauthor's claim.
The very high value of r2 confirms theauthor's claim.
The very low value of r2 denies the author'sclaim.
