This statistical analysis does not account for the fact that there is such a thing as 'nervous cough' which is anxiety-related. Stress hormones are likely to spike during stressful moments around the time a question is asked which may trigger a cough reflex from audience members. The analysis seems to focus on the wrong things. A proof of cheating should focus more on identifying specific and reliable patterns in the coughs. I don't think generic statistical analysis of this kind makes a strong case at all.
