a. 0.8284
b. 0.0233
c. 0.9131
d. 0.0183
e. 0.9535
Work Step by Step
Use the table in the appendix to get the area A(z) to the left of a Z value.
a. A(1.10)=.8643, A(-1.80)=.0359, A(1.10)-A(-1.80)=.8643-.0359=0.8284
b. 1-A(1.99)=1-.9767=0.0233
c. 1- A(-1.36)=1-.0869=0.9131
d. A(-2.09)=0.0183
e. A(1.68)=0.9535
