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 $z=- 1.04$ in the standard - normal distribution. The total area under the standard - normal curve is 1. The area to the left of $z = - 1.04$ can be found from the standard normal (z -) table.

Step2: Look up value in z - table

Looking up $z=-1.04$ in the standard normal table, the area to the left of $z = - 1.04$ is $0.1492$.

Step3: Calculate area to the right

The area to the right of $z=-1.04$ is $A = 1-0.1492$.
$A=0.8508$

Answer:

$0.8508$
