What is the area to the left of z 2?
The required area is 0.97725. Equivalently, one can use Excel's command =NORMSDIST(z) function. Simply replacing z with 2, we would find the required area of 0.97725.
What is the area to the right of z?
To find the area to the right of the z-score, we can simply look up the value -1.07 in the z-table: What is this? This represents the area to the left of z = -1.07. Thus, the area to the right is calculated as 1 – 0.1423 = is 0.8577.

How do you calculate the z-score?
How do you calculate the z-score? The formula for calculating a z-score is is z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation. As the formula shows, the z-score is simply the raw score minus the population mean, divided by the population standard deviation.

What is the z-score in statistics?
A Z-score is a numerical measurement that describes a value's relationship to the mean of a group of values. Z-score is measured in terms of standard deviations from the mean. If a Z-score is 0, it indicates that the data point's score is identical to the mean score.
Is z-score same as standard deviation?
Z-score indicates how much a given value differs from the standard deviation. The Z-score, or standard score, is the number of standard deviations a given data point lies above or below mean. Standard deviation is essentially a reflection of the amount of variability within a given data set.
