Question

find the area of the shaded region. the graph depicts the standard normal distribution of bone density scores with mean 0 and standard deviation 1. the area of the shaded region is (round to four decimal places as needed.)

Explanation:

Step1: Use z - table concept

We need to find the area to the right of $z=- 1.11$ under the standard - normal curve. The total area under the standard - normal curve is 1. The z - table gives the area to the left of a given z - value.

Step2: Look up value in z - table

Looking up $z =-1.11$ in the standard normal (z -) table, the area to the left of $z=-1.11$ is $0.1335$.

Step3: Calculate area to the right

The area to the right of $z=-1.11$ is $A = 1-0.1335$.
$A=0.8665$

Answer:

$0.8665$
