Linear Regression Analysis (Least Squares Method) We will also use the Regression Analysis Tool to determine the slope and intercept of the "best-fit" straight line through our data. R2. Now, answer the questions below using the plot you generated. What is the value of the correlation coefficient, R2 ? Tries 1/20 Previous Tries What is the value of the slope? Tries 6/20 What is the concentration of this solution that has an absorbance of 0.3200 a.u.? M Tries 1/20 What would be the expected absorbance of a 0.0650 M solution under the same conditions? a.u. Tries 0/20
