Standard Normal Distribution. In Exercises, 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.

Answer

Step 1 of 1 :

In finding the area under the standard normal curve,we can use the statistical tables at the black of your textbook or use your calculator.

In using the tables,remember this the area are reported as P(z < a)

Then,

P(z > a) = 1- p(z < a)

P(a < z < b) = p ( z < b) - p( z < a )

Applying this principle,We get

P(z < 0.44) = 0.6700 (using area under normal curve table )

Therefore P(z < 0.44) = 0.6700
