Question

find the indicated probability. use the standard normal distribution to find p(-2.50 < z < 1.50). 0.5496 0.6167 0.8822 0.9270

Explanation:

Step1: Recall the property of standard - normal distribution

$P(-2.50

Step2: Use the standard - normal table

From the standard - normal table, $P(z < 1.50)=0.9332$ and $P(z<-2.50)=0.0062$

Step3: Calculate the probability

$P(-2.50 < z<1.50)=0.9332 - 0.0062=0.9270$

Answer:

0.9270
