The data from Technometrics described in Exercise 8-56 considered the variability in repeated measurements of the weight of a sheet of paper. In summary, the sample standard deviation from 15 measurements was 0.0083 grams. (a) Does the measurement standard deviation differ from 0.01 grams at a = 0.05? Find the P-value for this test. (b) Discuss how part (a) could be answered by constructing a confidence interval for o. %3D
