The Tietjen and Moore paper gives the following set of 8 mass spectrometer measurements on a uranium isotope: 199.31, 199.53,
200.19, 200.82, 201.92, 201.95, 202.18, and 245.57. Use Grubbs test to decide if the maximum value is an outlier.
A The data should be retained.
B It is an outlier.
More information is needed to come up with a decision.
D) It is not an outlier.
