According to a Pew Research Center nationwide telephone survey of American adults conducted by phone between March 15 and April 24, 2011, 75% of adults said that college education has become too expensive for most people and they cannot afford it (Time, May 30, 2011). Suppose that this result is true for the 2011 population of American adults. In a recent poll of 1600 American adults, 1160 said that college education has become too expensive for most people and they cannot afford it. Using a 1% significance level, perform a test of hypothesis to determine whether the current percentage of American adults who will say that college education has become too expensive for most people and they cannot afford it is lower than 75%. Use both the p-value and the critical-value approaches.
