Method of Least Squares, Evaluation of Cost Equation Lassiter Company used the method of least squares to develop a cost equation to predict the cost of moving materials. There were 80 data points ft the regression, and the following computer output was generated: Intercept $19,050 Slope Coefficient of correlation 0.91 Standard error $220 The activity driver used was the number of moves. Required: 1. What is the cost formula? 2. Using the cost formula, predict the cost of moving materials...

using microsoft excel, plot the absorbance (y-axis) vs. the concentration of each FAS standard standard (in g/ml) Use the method of least squares (linear regression) to determine the slope, intercept, and correlation coefficient. Compare your slope with the literature value of 11,100 liter*mol^-1*cm^-1. You will have to convert your slope to have the same units as the literature value. Please do this unit conversion in your notebook. (FW FAS=392.13) Absorbance was read at 508 nm in a 1 cm curvette....
