If X is a normal variable with mean mu and standard deviation sigma, then the mean and standard deviation of the variable Z = (X - mu)/sigma is
- A. 1 and 0 respectively
- B. mu and sigma respectively
- C. 0 and 1 respectively
- D. None of these
Answer: C. 0 and 1 respectively
Explanation: For a standard normal variable Z = (X - mu)/sigma, the mean is 0 and the standard deviation is 1.
