In April 2010, 47% of the unemployed had been out of work longer than six months. Policy makers felt that this percentage declined during 2010 as the job market improved. To test this theory, a random sample of 300 unemployed people was selected, and it was found that 125 had been out of work for more than six months. Using alphaequals0.10, answer parts a through c below. a. What conclusions can be drawn about the proportion of the unemployed who have been out of work for more than six months? Determine the null and alternative hypotheses. Choose the correct answer below. A. Upper H 0: pgreater than or equals0.47 Upper H 1: pless than0.47 B. Upper H 0: pequals0.47 Upper H 1: pnot equals0.47 C. Upper H 0: pless than or equals0.47 Upper H 1: pgreater than0.47 D. Upper H 0: pgreater than0.47 Upper H 1: pless than or equals0.47 Determine the critical value(s) of the test statistic. z Subscript alphaequals nothing (Use a comma to separate answers as needed. Round to two decimal places as needed.) Calculate the test statistic. z Subscript pequals nothing (Round to two decimal places as needed.) Determine the conclusion. Choose the correct answer below. A. Do not reject Upper H 0. There is not sufficient evidence to conclude that the proportion of the unemployed who have been out of work for
