A Harris Poll found that 54% of American adults dont think that human beings developed from earlier

Question:

A Harris Poll found that 54% of American adults don’t think that human beings developed from earlier species. The poll’s margin of error for 95%

confidence was 3%. This means that

(a) there is a 95% chance that the interval (51%, 57%)

contains the true percent of American adults who do not think that human beings developed from earlier species.

(b) the poll used a method that provides an estimate within 3% of the truth about the population 95%

of the time.

(c) if Harris takes another poll using the same method, the results of the second poll will lie between 51%

and 57%.

(d) there is a 3% chance that the interval is correct.

(e) the poll used a method that would result in an interval that contains 54% in 95% of all possible samples of the same size from this population.
