Question

Calculate the standard score of the given x value, x=37.4, where x‾=32.6, s=4.8. Round your answer to two decimal places.

Answer 1

EXPLANATION

The equation of the standard z-score os the following:

$z=\frac{X-\bar{x}}{\sigma}$

Where x=37.4, x‾=32.6 σ=4.8

Plugging in the terms into the expression:

$z=\frac{37.4-32.6}{4.8}$

Subtracting numbers:

$z=\frac{4.8}{4.8}$

Simplifying:

$z=1$

In conclusion, the solution is z=1
