Astronomy students and the Big Bang Theory. Indiana University professors investigated first-year college students’

knowledge of astronomy (Astronomy Education Review, Vol. 2, 2003). One concept of interest was the Big Bang theory of the creation of the universe. In a sample of 148 freshman students, 37 believed that the Big Bang theory accurately described the creation of planetary systems.

Based on this information, would you be willing to state that more than 20% of all freshman college students believe in the Big Bang theory? How confident are you of your decision?
