Perform an appropriate analysis to determine if their claim is supported by evidence. You will do the analysis based first on the data from the first interview, creating subsets of the data file using daycode = 1, and a second time using data from the second interview, creating subsets of the data file using daycode = 2. Note differences in the results between the first and second interviews.
