Answer #1

For comparing the number of siblings of a student to the number of pets he have, we can use the Chi-square test as this test is used to compare two variables and to see how they are related to each other.

To compare the number of siblings of a student from Asia to that of North America, we can use the two proportion test as this test is used to compare how the two groups differ for the same characteristic.

For comparing the self reported tech skills of students whoplay video games and to those who do not we can use the two means test, as here we can compare the difference between the means of both the population with respect to technical skills.
