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.
Z= - 0.83 z= 1.24
The area of the shaded region is ___.
Solution:
P(-0.83 < z < 1.24)
= P(z < 1.24) - P(z < -0.83)
= 0.8925 - 0.2033 Using standard normal table,
Area = 0.6892
The area of the shaded region is 0.6892.
