7. Find the indicated z score: If area A + area B =.01, z = __________ A B – z 0 z  2.575 or  2.58 =.005

8. Application of Determining z Scores The Verbal SAT test has a mean score of 500 and a standard deviation of 100. Scores are normally distributed. A major university determines that it will accept only students whose Verbal SAT scores are in the top 4%. What is the minimum score that a student must earn to be accepted?

9. ...students whose Verbal SAT scores are in the top 4%. Mean = 500, standard deviation = 100 =.04.9600 z = 1.75 The cut-off score is 1.75 standard deviations above the mean.

10. Application of Determining z Scores Mean = 500, standard deviation = 100 =.04.9600 z = 1.75 The cut-off score is 500 + 1.75(100) = 675.
