Find the area of the shaded region. the graph depicts the standard normal distribution with mean 0 and standard deviation 1
z=0.65

The area of the shaded region as depicted by the graph is 0.7422

The formula for calculating the z-score is expressed as:

Given the following

The z-score of the distribution from the distribution table for z = 0.65 is 0.7422

Substituting the given values into the formula:

Hence the area of the shaded region as depicted by the graph is 0.7422

0.74215

Step-by-step explanation:

Given: Mean= 0

          Standard deviation= 1

          Z= 0.65

First lets find the z score of 0.65 from the normal distribution table.

∴ The value from the table is

Now using the formula for z-score to find x, which is the shaded region.

Z-score=

⇒

Multiplying both side by 1

∴

Hence, the area of shaded region is 0.74215.
