Refer to Exercise 6.9. Could we run a t test comparing the mean metal concentrations for magnesium and europium? Why or why not?

REFERENCE:

6.9 : The study of concentrations of atmospheric trace metals in isolated areas of the world has received considerable attention because of the concern that humans might somehow alter the climate of the earth by changing the amount and distribution of trace metals in the atmosphere. Consider a study at the south pole, where at 10 different sampling periods throughout a 2-month period, 10,000 standard cubic meters (scm) of air were obtained and analyzed for metal concentrations. The results associated with magnesium and europium are listed here. (Note: Magnesium results are in units of europium results are in units of Note that for the magnesium data. Would you expect the data to be normally distributed? Explain.
