According to a Pew Research Center nationwide telephone survey of adults conducted March 15 to April 24, 2011, 69 % of college graduates said that their college education gave them maturity (Time, May 30, 2011). Suppose that this survey included n = 1440 college graduates. a. What is the point estimate of the corresponding population proportion? p ^ = Enter your answer; point estimate b. Construct a 97 % confidence interval for the proportion of all college graduates who will say that their college education gave them maturity. What is the margin of error for this estimate? Round your answers to three decimal places.
