In April 2010, 49% 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 500 unemployed people was selected, and it was found that 233 had been out of work for more than six months. Using a=0.10, 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. ns OA Ho: p=0.49 H₁ p*0.49 OC. Ho: ps0.49 H₁: p>0.49 Determine the critical value(s) of the test statistic OB. Ho:p>0.49 H₁: ps0.49 D. H₂:20.49 H₁: p<0.49 urce Z-1.28 (Use a comma to separate answers as needed. Round to two decimal places as needed.) Calculate the test statistic
