The General Social Survey is an annual survey given to about 1500 U.S. adults selected at random. A recent survey contained the question "How important to your life is having a fulfilling job?" Of the 222 college graduates surveyed, 94 chose the response "Very important." Of the 106 people surveyed whose highest level of education was high school or less, 32 chose the response "Very important."Based on these data, can we conclude, at the 0.01 level of significance, that there is a difference between the proportion p1 of all U.S. college graduates who would answer "Very important" and the proportion p2 of all U.S. adults whose highest level of education was high school or less who would answer "Very important"? Perform a two-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places and round your answers as specified in the parts below. (If necessary, consult a list of formulas.) A. State the null hypothesis H0 and the alternative hypothesis H1 B. Find the value of the test statistic. (Round to three or more decimal places.) C.
