A) Give a complete analysis of the following data collected for the % of sulfate in a sample: 17.26%, 17.48%, 18.85%, 16.88%, 15.74%, 17.68%. For the analysis assume that the actual % of sulfate in the sample was found to be 16.95%. If any of the data can be discarded at the 95% confidence level, be sure to give complete explanation.
B) Calculate the absolute standard deviation for the value 17.26% if this value was obtained from the following data: weight of barium sulfate collected = (56.8361 +/- 0.0001g - 51.0915 +/- 0.0001g), weight of sulfate = answer x (96.034/233.391), weight of sample = (104.7715 +/- 0.0001g - 91.0768 +/- 0.0001g)
