A sample with mean of 85 and SD of 12 is transformed into z-scores. After the transformation, what are the values for the mean a
nd standard deviation for the sample of z-scores
1 answer:
Answer:
The value remain unchanged.
Step-by-step explanation:
By Z score, we mean:
Z = 
, if we substitute the given values of mean and standard deviation, we obtain the z score value. That is,
Z = 
= 85/12 = 7.083333.
NB: We assume that mean and standard deviation are in the same units.
