Coulrophobia, or the extreme or irrational fear of clowns, is considered to be relatively rare. A 2018 study conducted by Chapman University found that, in a representative sample of 1190 American adults, 3% indicated they were "very afraid" of clowns. A 99% confidence level created from these data is (0.0173, 0.0426) . Which of the following statements best interpret the 99% confidence level?
A) We can say, with 99% confidence, that the proportion of the 1190 American adults surveyed who were "very afraid" of clowns is between 0.0173 and 0.0426.
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.
D) We would expect roughly 99% of 99% confidence intervals (each created from a different sample) to contain the long-run proportion of American adults who are "very afraid" of clowns.
