Linear Regression Analysis (Least Squares Method) Analysis Tool to determine the slope and intercept of the "best-fit" straight line through our data. Now, answer the questions below using the plot you generated. What is the value of the correlation coefficient, \( \mathrm{R}^{2} \) ? \( 0.9802 \) Previous Tries What is the value of the slope? What is the concentration of this solution that has an absorbance of \( 0.3200 \) a.u.? \( M \) Tries 2/20 Previous Tries What would be the expected absorbance of a \( 0.0650 \mathrm{M} \) solution under the same conditions? a.t. Trles \( 0 / 20 \)
