$1.$ Using the Excel functions SLOPE$(),$ INTERCEPT$(),$ and RSQ$(),$ calculate the linear model fitting parameters and R$2$ for a simple linear fit of mass vs time. Next, calculate the same parameters for a fit of ln$($mass$)$ vs time. Finally, calculate the same three values for a fit of ln$($mass$)$ vs ln$($time$).$ For situations in which your fitting data includes an error $($denoted $$#NUM!$),$ simply omit the relevant data point from the range you enter into the Excel function.

Create a table with appropriate row and column labels to report the values of the slope, intercept, and R$2$ for each of the three cases described above. Copy this table into your Word document. Which case gives the $$best fit$$ to the data set?
