A11.) 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 corrected for the buoyancy factor and divide by the density of the water. The result of 8 such measurements is given in the table. The standard deviation for the data set is 0.0219. Measurement Volume (mL) 1 10.052 10.050 3 10.022 4 10.056 10.025 10.005 7 10.064 8 10.015 a.). Calculate the mean and the 95% confidence interval for these measurements. Report the value for the mean with the correct number of significant figures based on 95% confidence interval using the "real rules" for significant figures. b.). Can you say with 95% confidence that the nominal value of 10.00 mL can be the true volume of the flask?

Background: Henry Cavendish carried out a series of experiments in 1798 to determine the mean density of the earth, as an indirect means to calculate the gravitational constant. A measurement of 5.5 indicates the earth's density is 5.5 times that of water. 1.Perform the significance test. A.H0: μ=5.513Ha: μ>5.513 B.H0: μ=5.513Ha: μ<5.513 C.H0: μ=5.513Ha: μ≠5.513 D. H0: μ≠5.513Ha: μ=5.513 2.Compute the test statistic. Round your answer to 4 decimal places. 3.Compute the p-value. Round your answer to 4 decimal places.
