Answer to 10.57c in Solutions Manual is wrong. 10.57 Assumptions: “The sum of the YN and the NY counts are greater than 30à 515+290 >30. Assumption Met. Ho: p1-p2=0 Ha: p1-p2 does not equal 0 Test Statistics = z= (515 – 290) / sqrt(515+290) = 7.93 P-value equals the probability less than 7.93 and the probability greater than 7.93 = almost zero With a p-value of almost zero, there is strong evidence that there is a difference in the proportion of people of re-arrest for juveniles who are seen in an adult court and for juveniles that are seen in a juvenile court.
