Question

household income in a large city is best represented by a histogram skewed to the left. student scores on a difficult exam is best represented by a histogram skewed to the right. age of death from natural causes is best represented by a histogram skewed to the select. age of retirement is best represented by a histogram skewed to the select.

Explanation:

1. Household income in a large - city: There are usually a small number of high - income households. So, the tail of the income distribution is on the right side, and the histogram is skewed to the right.
2. Student scores on a difficult exam: Most students will get relatively low scores, and only a few students will get high scores. So, the tail of the score distribution is on the right side, and the histogram is skewed to the right.
3. Age of death from natural causes: There are very few cases of early death from natural causes, and most people die at relatively older ages. So, the tail of the age - of - death distribution is on the left side, and the histogram is skewed to the left.
4. Age of retirement: Most people retire around the normal retirement age, and there are fewer people who retire much earlier or much later. The tail of the age - of - retirement distribution is on the right side (due to some people retiring later), and the histogram is skewed to the right.

Answer:

Age of death from natural causes: left
Age of retirement: right
