We feel this is justified as the reported figures show what percentage of all respondents (including those who were uncertain) agree with the questions we asked. In Table 3 panel B and Table 4, panel C we report the percentage of respondents who selected each item. Some respondents did not answer all the questions in the survey, their reasons are unknown (e.g. questionnaire is too long, not interested, etc).We find no significant differences in the responses of those who answered the questionnaire from start to finish and those who didn’t.5
