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: 0.3205%, 0.3202%, 0.3196%, 0.3198%, 0.3316%, 0.3197%, 0.3208%, and 0.3197%. Calculate the mean (x) and standard deviation (s) for these results.

Transcribed Image Text: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: 0.3205%, 0.3202%, 0.3196%, 0.3198%, 0.3316%, 0.3197%, 0.3208%, and
0.3197%.
Calculate the mean () and standard deviation (s) for these results.
x =
Use the Grubbs test to determine if one of these values is an outlier. What is the value of Gealeulated?
Gcalculated =
