For a population with µ = 100 and σ = 20, what is the X value corresponding to z = -0.75?​
Savatey [412]

The X value corresponding to z = -0.75 will be 85. Then the correct option is A.

<h3>What is the z-score?</h3>

The z-score is a statistical evaluation of a value's correlation to the mean of a collection of values, expressed in terms of standard deviation.

The z-score is given as

z = (x - μ) / σ

Where μ is the mean, σ is the standard deviation, and x is the sample.

For a population with µ = 100 and σ = 20.

Then the X value corresponding to z = -0.75 will be

-0.75 = (x - 100) / 20

   -15 = x - 100

      x = 85

Then the correct option is A.

More about the z-score link is given below.
