Quizplus · Accepted Answer

Weights of 10-year-old boys and the amount of coffee filled by a machine into jars are likely to be normally distributed due to natural variation around a mean (for weights) and precision around a target measure (for coffee filling), respectively. Incomes are often right-skewed, and dice rolls have a uniform distribution, not normal.
