The scores on a certain standardized test follow a normal distribution. The mean score is 76, and the standard deviation is 8.
Inessa [10]

About 4.01% of the test scores in the normal distribution that are greater than 90

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more number and variables.

Z score is given by:

z = (raw score - mean) / standard deviation

Given that mean score is 76, and the standard deviation is 8.

For x > 90:

z = (90 - 76) / 8 = 1.75

P(z > 1.75) = 1 - P(z < 1.75) = 1 -  0.9599 = 0.0401

About 4.01% of the test scores in the normal distribution that are greater than 90
