Question

What is the z-score of the value 724 rounded to the nearest tenth?

Answer 1

In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data:

mean = 571

standard deviation = 236.5

score = 724

Step 02:

z-score:

`z-score\text{ = }(x-\mu)/(\sigma)=(724-571)/(236.5)=(153)/(236.5)=0.6`

The answer is:

z - score = 0.6
