Question

Dr. Caras was characterizing a cytochrome (an iron containing protein) from a new strain of bacteria. He obtained the following values in eight measurements of the percent iron in the protein: 0.5506%, 0.5501%, 0.5498%, 0.5495%, 0.5615%, 0.5499%, 0.5508%, 0.5497% Calculate the mean (R) and standard deviation (s) for these results. Number 七一 e the Grubbs test to determine if one of these values is an outlier. What is the value of Geataulited? Should this potential outlier be rejected with 95% confidence? Critical values of G can be found in the following table. O The potential outlier should be kept O The potential outlier should be rejected. Number rint
