Answer:

z-score is calculated by:

z = (value - mean)/std

  = (4100 - 3550)/870

  = 0.632

=> Option B is correct.

Hope this helps!

The z- score of the question is  0.632. Hence,  Option B is correct.

What is a z- score?

The z-score is a numerical measurement used in statistics to refer to how much a given value differs from the standard deviation.

Using the usual notations and formulas,

mean, mu = 3550

standard deviation, sigma = 870

Observed value, X = 4100

Therefore, z-score is calculated by:

z = (value - mean)/std

 = (4100 - 3550)/870

 = 0.632

Hence,  Option B is correct.
