Chapter 12, Problem AP4.15(choose chapter or problem)
A Harris Poll found that 54% of American adults dont think that human beings developed from earlier species. The polls 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. AP4
