Answer

Explanation:

Step1: Recall standard - normal table usage

The standard - normal table gives the cumulative area from $z =-\infty$ to a given $z$ value.

Step2: Find cumulative area for $z = 1.5$

Looking up $z = 1.5$ in the standard - normal table, we get $A_1=\Phi(1.5)=0.9332$.

Step3: Find cumulative area for $z=-1.3$

Looking up $z = - 1.3$ in the standard - normal table, we get $A_2=\Phi(-1.3)=0.0968$.

Step4: Calculate the area between the two $z$ - values

The area between $z=-1.3$ and $z = 1.5$ is $A=A_1 - A_2$. So, $A=0.9332-0.0968 = 0.8364$.

Answer:

$0.8364$
