Graph all four data sets on the same graph and show the appropriate regression and r-square for each (10). Find and justify which set of data is errorless. Identify and justify the errors (positiveegative, random/systematic- constant/proportional) in the other three sets of data. Calculate the %error in the half-life. For the errorless data set, calculate the starting number of nuclides, N. File > Make a copy and rename: YourName_Rad_decay_data_analysis_activity Complete the table below.
