Concept:Wages of workers in a factory are continuous and tend to cluster around a mean, forming a symmetrical bell-shaped curve.Explanation:The wages of a large number of workers typically follow a Normal distribution due to the central limit theorem and the nature of continuous, symmetric data.Other options are incorrect because: Binomial and Poisson are discrete distributions (for counts or successes), and Chi-square is skewed and non-negative.Answer:Normal distribution
