Answer
The statement is inferential.
Work Step by Step
As mentioned in the description part of the exercise, this survey was conducted on a random sample of adult Americans.
Therefore, when such a statement as the results of the survey indicate that $8\%$ of adult Americans believe that divorce is acceptable in certain situations, the statement is deduced from the fact that $8\%$ of a random sample of adult Americans taking the survey believe so.
So, the statement had been inferred from the survey. It is an inferential statement.
