The value of the z-score will be equal to -0.93.
What is z-score?
A z-score, also known as the standard score, is a calculation used to determine how many standard deviations a raw score is below or above the population mean.
Simply said, the Z Score informs you of a value's relationship to the mean and the distance a data point is from the mean.
Given that Evan's current weight is 133 pounds. Their mean weight of Evan is 147 pounds. with a standard deviation of 15 pounds.
The x-score is calculated by the formula,
z = ( x - μ ) / (σ)
z = ( 133 - 147 )/ (15)
z = -0.93
Therefore, the value of the z-score will be equal to -0.93.
