3. Consider this data for the mass (in g) of a precipitate: 4.06, 4.00, 3.70, 3.95, and 4.02. (a) Compute the average and standard deviation in the mass (do not show work). Can any of these points be discarded using the Grubbs test? Explain, show work. (b) Using all remaining data points (do not include any points that you discarded), com pute the best 95% confidence interval in the mass. Report the mean and confidence interval to the correct number of figures. Show all work.
