(a) Use the method of least squares to determine the expression for the estimated regression line. slope = intercept: (b) Compute the sample standard deviation for final product weight (use the stats function on the y variable). sample standard deviation = (c) Compute the standard error of the estimate for final product weight. standard error of the estimate = (d) Determine the predicted final product weight when the volume of raw material in gallons is 10 gallons predicted value =
