According to a Pew Research Center nationwide telephone survey of adults conducted between March 15 and April 24, 2011, 55% of college graduates said that college education prepared them for a job (Time, May 30, 2011). Suppose this result was true of all college graduates at that time. In a recent sample of 1950 college graduates, 59% said that college education prepared them for a job. Is there significant evidence at a 10% significance level to conclude that the current percentage of all college graduates who will say that college education prepared them for a job is different from 55%? Use both the p-value and the critical-value approaches. Round your answers for the observed value of z and the critical value of z to two decimal places, and the p-value to four decimal places. Enter the critical values in increasing order. Zobserved p-value - Critical values: and We can conclude that the current percentage of all college graduates who will say that college education prepared them for a job is v 55%.
