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 15 90 American adults, 1165 said that college education has become too expensive for most people and they cannot afford it. Using a 10% signicance 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 pvalue and the critical-value approaches. Round your answers for the observed value ofzand the critical value ofzto two decimal places, and the pvalue to four decimal places. Critical value = n We can conclude that 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 75%. less than not less than eTextbook and Media
