$($a$)$ Best$-$fit functions you found $($fit both linear and quadratic model$),$ and the associated squared

errors.

$($b$)$ Plot of original data, and then on the same graph, plot the fitted data from best$-$fit models $($use

different colors and plot types, e$.$g$.,$ plot$($fit$1,$r$*)$ would plot the fit$1$ data as red asterisks;

plot$($fit$2,$g$+)$ would plot green plus signs. Give a key for the plots$).$

$($c$)$ Conclusions $-$ what was the best model and why? Are there any properties of the materials involved

that could have caused the results you observed? Can you complete all parts using the following table.
