Explanation:

1. For the number of children per household, most households have a small number of children, with a few having a large number. So, the tail of the distribution is on the right - side, and it is right - skewed.
2. For student scores on an easy exam, most students will score high, with a few scoring low. So, the tail of the distribution is on the left - side, and it is left - skewed.
3. For the number of points taken off students' grades on a difficult exam, most students will have a large number of points taken off, with a few having a small number. So, the tail of the distribution is on the right - side, and it is right - skewed.
4. For household income in a large city, most households have a relatively low income, with a few high - income households. So, the tail of the distribution is on the right - side, and it is right - skewed.
