A population with = 85 and = 12 is transformed into z-scores. After the transformation, what are the values for the mean and standard deviation for the population of z-scores?
| A. = 85 and = 12 |
| B. = 0 and = 12 |
| C. = 85 and = 1 |
| D. = 0 and = 1 |
| A.X = 70 |
| B.X = 68 |
| C.X = 64 |
| D.X = 60 |
