Standardize a Normally Distributed Random Varlable Question Suppose X~N(13.5, 1.5), and 9. Find and interpret the z-score of the standardized normal random variable. Sorry, that's incorrect. Try again? The mean is The z-score when x-9 is standard deviations to the left of the mean. This z-score tells you that x-9 is Standardize a Normally Distributed Random Varlable Question Suppose X~N(13.5, 1.5), and 9.
