An analysis of a sample containing mercury was performedusing a standard procedure and a new procedure. The samplewas analyzed 6 times by the new procedure and 8 times by thestandard procedure resulting in standard deviations of 0.355 and0.524 for the new and standard procedures, respectively. If thepooled standard deviation for the data was 0.66 and thetabulated F value at the 95% confidence level was 4.88, Thefollowing statement(s) are true:Select one or more:A. The calculated F value is 2.179B. We are confident that there is no significant statisticalC. difference between the results of the two methodsD.

1. Research on the limitation of accuracy of the following instruments: • analytical balance • top-loading balance • serological pipette • graduated cylinder • burette • volumetric flask • Erlenmeyer flask • beaker 2. Define the term, "measurement uncertainty". Among the instruments listed above, which ones have the highest uncertainty? Which ones have the lowest? 3. Based on the measurement uncertainty of the above instruments, which instruments would yield the lowest percent error?
Consider the following sets of replicate measurements. For each set, calculate the (a) mean; (b) median; (c) spread, or range; (d) standard deviation; (e) coefficient of variation; and (f) RSD. Then calculate for spooled value of the whole data set.
