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.
