The value of z-score for a mean of 2 and the standard deviation of 1 is 1.
A Z-score helps us to understand how far is the data from the mean. It is a measure of how many times the data is above or below the mean. It is given by the formula,
[tex]Z = \dfrac{X- \mu}{\sigma}[/tex]
Where Z is the Z-score,
X is the data point,
μ is the mean and σ is the standard variable.
As it is given that the value of mean is 2, while the value of the standard deviation is 1. therefore, for the value of x as 3,
[tex]Z = \dfrac{X- \mu}{\sigma}\\\\Z = \dfrac{3- 2}{1}\\\\Z=1[/tex]
Hence, The value of the z-score for a mean of 2 and the standard deviation of 1 is 1.
