[Coco] Re: The typical CoCo user is aged...?!?

The known population that now currently uses the Coco is uncertain. That actually 
can not be determined without an exhaustive detailed study.

In this case the population is unknown. Yet a sample size of 32 is a significant 
number. The sample size of 57 is even better. I also stated that this sample is a 
good indication of the users at this time. The fact is that the sample yielded two 
distinct peaks of user ages.

I never stated that it was indeed a prediction of the overall population. I do state that 
the sample size is significant and that some general conclusions can be drawn from 
the small sample size. Yes even a sample size of 32 can yield significant 
conclusions. Not definitive conclusions. 

I contend that if the sample size eventually grew to 200, there still will yield two 
peaks in the age distribution. I cannot state which one will be larger. I can not 
determine exactly what ages are the two peaks. Though I can be confident that 
there will be two peaks.
