Dr. Caras was characterizing a cytochrome (an iron containing protein) from a new strain of bacteria. He obtained eight
measurements of the percent iron in the protein: 0.4908%, 0.4902%, 0.4899%, 0.4899%, 0.5012%, 0.4891%, 0.4903%, and
0.4892%.
Calculate the mean (x) and standard deviation (s) for these results.
