Need help calculating and understanding Analytical Chemistry problem?

A Volumetric analysis of Ca^2+ in calcium supplement pills was performed. The results of the %Ca in the pills are shown below. An analysis of the supplement was performed by NIST and the "true" value was determined to be 21.79%. Does the volumetric method agree with the "true" value at the 90%... show more A Volumetric analysis of Ca^2+ in calcium supplement pills was performed.
