If a z-score is zero, which of the following must be true? Explain your reasoning.
A. The mean is zero.
B. The corresponding x-value is zero.
C. The corresponding x-value is equal to the mean.

The correct answer is (C)

Explanation:

To find the z-score the most important factors are the standard deviations, the mean and the variance. Likewise, if the corresponding x-value is equal to the mean and mean is zero, then the z-score will be zero because mean and z-score are always equal. Overall, z-score is used to measure the statistical relationship between groups based on the standard deviation from the mean.
