To apply the least least-square method, set the variable y = V and the variable x = 100 12.1 +0.2 150 16.9 + 0.3 200 Ex,= 24.2 + 0.3 250 29.3 + 0.4 300 35.8 + 0.5 350 41.7 + 0.6 400 47.3 + 0.7 n = 450 54.0 + 0.8 0 = 500 59.5 + 0.8 Results of the least-squares fit: - Slope: m= - y-intercept: b= . Analytical interpretation of the fit parameters m and b, based on the well known relation between the mass and the volumen of a disk. Using the previous analytical interpretation and the results of the fit, obtain expressions for the density p and it's uncertainty. Hint: your expression should include some of the variables m, b, Am or Ab. P = Ap = Numeric value: P =
