Lab 1: Measurement and Uncertainty Assignment Calculate the slope of your trendline for your hand-drawn graph. Show your work. '5'O'xv 1:3: 331"" Csv97'5L/D Now use Excel to recreate the same plot, but this time let the computer find the slope. Cut and paste the graph from Excel into your document, or submit the Excel le along with this assignment, if you prefer. Be sure that the data points and the equation of the line are visible, and submit it as part of your lab report. Report the value of 11 obtained from the Excel trendline, with an appropriate number of signicant digits.1 Show your work (or explain how you found this result). 10. Compare your Excel answer for the value of TE with the known value by calculating the percent error. Show your work.
