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

Step-by-step 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=(37.4-32.6)/(4.8)`

Subtracting numbers:

`z=(4.8)/(4.8)`

Simplifying:

`z=1`

In conclusion, the solution is z=1
