The formula for computing a Z-score is (x - mean) / sd, where x is the value being standardized, mean is the mean of the data set, and sd is the standard deviation of the data set. Therefore, the correct formula is (x - mean) sd, which is option C.

To Compute a Z-Score, Which of the Following Formulas Would (y−mean)sd \frac{(\text{y} - \text{mean}) }{\text{sd}} sd(y−mean)​
