For the final project of an analytical chemistry laboratory course, the students were asked to quantify the lead (Pb2+) content in a drinking water sample. To receive a passing grade for the project, the students must produce a result (Pb2 concentration) that agrees with the result obtained by the course professor, who was using the same method, at the 95% confidence level. The mean (x), standard deviation (Sy) and number of replicate measurements (n) are shown below for the data...
