The mass percent of KHP in an unknown salt sample was determined using both volumetric and gravimetric titration. Ten determinations using each method were performed: Volumetric (% KHP): 34.22 33.86 34.07 34.49 34.69 33.71 34.28 34.11 34.26 34.10 34.18 34.32 34.11 34.33 34.17 34.12 Gravimetric (% KHP): 34.35 34.26 34.10 34.19 a) Do the two methods give similar standard deviations? b) Do the two methods give similar results for the mass percent of KHP at the 95% confidence level? c) What is the probability that the difference in the two data sets arises from random error?
