Unformatted text preview: measurement that represent + 1 standard deviation. Connect the data points using the linear least squares best fit, and report on the plot the equation of this best fit line and the R 2 value. 4. Report the value of the coefficient β for your electrode: 5. Report the concentration of F-(in mg L-1 ) in your tap water: 6. Provide an example of calculations you used to prepare the calibration curve, and to determine the coefficient β and the concentration of your unknown. One example for each type of calculation is sufficient....
