If 'Andy' is right as to these numbers: 10257 surveyed (population) 77 responded (sample size) 75 of responses were in the affirmative Then statistics tells us that the probability is 97.5% that more than 93% of the climate scientists (e.g. more than 9500 of the 10257) are in agreement with the survey, right? So THAT is really what should have been reported, thought he most probably number is 97%. -- FF
