Work Step by Step

The table in the appendix give the area A(z) to the left of a Z value. a. A(0)=0.5, A(1.95)=0.9744, A(1.95)-A(0)=0.4744, b. A(0)=0.5 A(0.37)=0.6443, A(0.37)-A(0)=0.1443, c. A(1.32)=.9066, A(1.82)=.9656, A(1.82)-A(1.32)=0.059 d. A(1.05)=.8531, A(2.05)=.9798, A(2.05)-A(1.05)=0.1267 e. A(0.03)=.5120, A(0.53)=.7019, A(0.53)-A(0.03)=0.1899
