B) Approximately 99% of the time, the true proportion of American adults who are "very afraid" of clowns is between 0.0173 and 0.0426.
C) In the long-run, we anticipate 99% of sample proportions of American adults who are "very afraid" of clowns to be contained in the 99% confidence interval provided.
