In a distribution with s = 20,a score that is above the mean by 10 points will have a z-score of z = 0.50.

To find the z-score, we use the formula:

z = (x - μ) / σ

where x is the raw score, μ is the mean, and σ is the standard deviation.

In this case, the raw score is 10 points above the mean, so we have:

z = (x - μ) / σ = (10 - 0) / 20 = 0.5

Therefore, the z-score for a score that is 10 points above the mean in this distribution is indeed 0.50.
