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.

FIND. Z=-0.89

The area of the shaded region would be? ______

Solutions

Expert Solution

(a)z=-0.89

the left of z is

P(z < -0.89)

Using z table  

area=0.1867

(C)

the right of z is

P(z >-0.89 ) =1 - P(z <-0.89 )

Using z table,
= 1 -0.1867

area= 0.8133
