Answer :
The Z-score if the mean is 5.5, the standard deviation is 2.3, and the x is 10.1, is given by z = 7.7
What is Z-score?
A z-score describes the position of a raw score in terms of its distance from the mean, when measured in standard deviation units.
Given that, we need to find the Z-score if the mean is 5.5, the standard deviation is 2.3, and the x is 10.1,
We know that,
z = 10.1−5.5/2.3, where μ is the mean and σ is standard deviation.
z = 10.1-2.4
z = 7.7
Hence, the Z-score if the mean is 5.5, the standard deviation is 2.3, and the x is 10.1, is given by z = 7.7
