  2. hundredths Z units tenths Cumulative probability in shaded area

  3. Area = probability = .8925 z = 1.24 Example: Z = 1.24 P(Z ≤1.24) = .8925 hundredths .04 Z units tenths Cumulative probability in shaded area 1.2 .8925

  4. Area = probability = .1075 z = -1.24 Example: Z = -1.24 P(Z ≤ -1.24) = .1075 hundredths hundredths -.04 Z units tenths .1075 -1.2
