The value of z-score for a score that is three standard deviations above the mean is 3.
In this question,
A z-score measures exactly how many standard deviations a data point is above or below the mean. It allows us to calculate the probability of a score occurring within our normal distribution and enables us to compare two scores that are from different normal distributions.
Let x be the score
let μ be the mean and
let σ be the standard deviations
Now, x = μ + 3σ
The formula of z-score is

⇒ 
⇒ 
⇒ 
Hence we can conclude that the value of z-score for a score that is three standard deviations above the mean is 3.

Answer:
5
Step-by-step explanation:
To find the median number of
3 7 5 2 4 2 53 6 9 7 7 3 5 2 7 3 2 2 7
Number them from least to greatest
2 2 2 2 3 3 3 4 5 5 6 7 7 7 7 7 9 53
Since this isn't an even numbered set, all we do is cancel each number out equally on both sides until only one number which should be in the middle is left. This gives you an answer of 5
Hope this helps!
