Reference no: EM13102701

A sample survey funded by the National Science Foundation asked a random sample of American adults about biological evolution. One question asked subjects to answer "True," "False," or "Not sure" to the statement "Human beings, as we know them today, developed from earlier species of animals." Of the 1484 respondents, 594 said "True." What can you say with 95% confidence about the percent of all American adults who think that humans developed from earlier species of animals.
