You are checking the accuracy of a volumetric flask marked 10.00 mL. To calculate the volume of water contained in the flask, you first measure the mass of the empty flask and the mass of the flask filled with water and take the difference. Then, you correct for the buoyancy factor and divide by the density of the water. The result of 8 such measurements is given in the table. Measurement Volume (mL) 1 10.059 2 10.050 3. 10.009 4 10.062 Calculate the mean and the 95% confidence interval for these measurements. 10.025 6. 10.019 10.049 8. 10.020 ml. 10.036 mean: 10.021 mL 95% confidence interval: + Incorrect
