Thread: Distribution models

In 1991 the BMI was measured for a random sample of 3204 men, 599 were found have a BMI of 30 or over hence obese ( somewhere in England...source withheld) and in 2001 from another random sample of 6267, 1316 were found to be obese.

What distribution provide models for the number of men in in each sample who are obese.

The wording of the question is a bit confusing, but I would have thought
that you might use a normal distribution for the distribution of BMI in the
population, and a binomial distribution for the number in the sample found to be obese.
