The use of nuclear magnetic resonance (NMR) spectroscopy for detection of malignancy is discussed in the journal Clinical Chemistry. The line width at the half height of peaks in the NMR spectrum is measured. The spectrum is produced from assaying plasma from an individual. Suppose the following line widths (measured in Hertz [Hz]) were obtained from a normal group and a group known to have malignancies. Would you reject a two tailed research hypothesis at the 0.05 level of significance?
