QUESTION:
Find the area under the normal curve
a. To the right of \(z=-0.85\).
b. Between \(z=0.40\) and \(z=1.30\).
c. Between \(z=?0.30\) and \(z=0.90\).
d. Outside \(z=?1.50\) to \(z=?0.45\).
ANSWER:Step 1 of 4:
Our goal is :
a). We need to find to the right of \(z=-0.85\).
b). We need to find between \(z=0.40\) and \(z=1.30\).
c). We need to find between \(z=-0.30\) and \(z=0.90\).
d). We need to find outside \(z=-1.50\) to \(z=-0.45\).
Now we have to find the area under the normal curve.
a). Given the area under the standard normal curve to the right of \(z=-0.85\).
\(Area=1-0.85\)
Using area under the normal curve table value.
\(Area=1-0.1977\)
\(Area=0.8023\) OR
\(P(z>0.85)= 1-P(z<0.85)\)
Using area under the normal curve table value.
\(P(z>0.85)= 1-0.1977\)
\(P(z>0.85)= 0.8023\)
Therefore the area under the standard normal curve to the right of \(z=-0.85\) is 0.8023.
