A forensic chemist runs High-Performance Liquid Chromatography-Mass Spectrometry (HPLC- MS) on seven hair samples from the same individual, suspect to contain traces of cocaine. The following concentrations were obtained in pg/mg: 1.8, 1.4, 0.75, 1.3, 1.6, 1.5, 1.7. Using the Grubb’s test, are there any outliers in the data? Show your work

Electrospray time‑of‑flight (TOF) mass spectrometry was used to analyze the eluate from a high‑performance liquid chromatography (HPLC) separation. The mass spectrum of one chromatographic peak, containing a protein of unknown molecular mass, displays MHnn+ peaks at m/z= 6636.908, 6194.524, 5807.480, 5465.932, 5162.360, and 4890.726. Find the average molecular mass (M) of the neutral protein and its standard deviation.
