Question
Chapter PSS, Problem 1ST
Interpretation Introduction
Interpretation:
The balance that has the least uncertainty is to be identified.
Concept Introduction:
Many instruments are used to measure physical quantities. The uncertainty in the value of an instrument is the measurement of the degree of inexactness in the reading of the instruments. The uncertainty of an instrument is represented with a pulse-minus sign because an error can be added or subtracted from the reading.

A volumetric calcium analysis on triplicate samples of the blood serum of a patient believed to be suffering from a hyperparathyroid condition produced the following data: mmol Ca/L = 3.55, 3.65, 3.14. What is the 95% confidence interval for the mean of the data, assuming(a) No prior information about the precision of the analysis?(b) s → σ = 0.056 mmol Ca/L?
Suppose that instead of using the cylindrical rod of Example 1-2 to prepare a 1.000 kgmass we were to use a solid spherical ball of copper What must be the radius of this ball?
A stock solution of 0.225 +/- 0.003 M NaNO2 was transferred to a 100 mL volumetric flask (class A) and diluted to the mark. If 7 mL of the stock solution was transferred using one 5-mL and two 1-mL volumetric pipettes, what is the new concentration of the solution and the uncertainty?
Please show how to calculate the uncertainty, that is the one part I don't understand how to do
