Quizplus · Accepted Answer

The thickness of a metal piece is a continuous random variable since it can take on any value within a range (e.g. 0.5mm, 0.7mm, 1.3mm, etc.). Poisson distribution is for count data, binomial distribution is for binary outcomes, and discrete random variables only take on a finite set of values (e.g. number of children in a family). Therefore, the best choice is continuous random variable.
