Answer 1

The domain for variable X is {ann, ben, cam, dave}. The statement that is true is: Because they can take any value within their domain, and their value for any particular case is not known until the survey is completed.

Step-by-step explanation:

The statement that is true is:

Because they can take any value within their domain, and their value for any particular case is not known until the survey is completed.

In this case, the random variables X, Y, and Z are considered random because they can take any value within their respective domains, which are {ann, ben, cam, dave} for X, a set of integers for Y, and any amount of money from zero upwards for Z. The specific value each variable takes is not known until the survey or experiment is completed.
