The following are a few guidelines that you must follow for the graphs: 2001 1. Your assignment should have a cover page including your name, course number, lab section, semester, and Date. ETEEN 2. For the precision graphs (graph 1) plot a scatter graph of the three replicates at each dilution. Each replicate should be clearly identifiable via color-coding o NOTE: do not do the graph in excel, do it by hand 3. For the accuracy graph, plot a graph of the average absorbance from each table as well as the predicted absorbance. Make sure the data are color-coded. end perereca o NOTE: predicted values are calculated from the average absorbance value of the stock solution (20x). From this value, the predicted absorbance values of the subsequent dilutions are calculated - your TA will explain this. then leabout 4. A clear and sufficiently descriptive title should be present, as well both axis with their corresponding unit far in 5. The graph should be at least half of an A4 page 6. The major unit of the y-axis should be at least 0.1, while the minor unit at least 0.02 Once you've drawn your graphs, write a short paragraph summarizing the conclusions you can make about the results of this experiment. (do not just describe your results). Discuss the results by stating the reasons behind the high or low precision that you obtained at specific concentrations
