Given a Normal Probability Distribution with p = 52 and will now calculate the z-score for the value x = 46 and then tell what the z-score means? ANSWER: 1) z score = 1 for X = 46 value for mean 52 and standard deviation = 6 => 2-(46-52)/6 =-1 2) This means that X-46 value is one standard deviation BELOW the mean of x-52 (Using formula for Z-score conversion of: YOU choose ANY OTHER X value on this normal distribution curve 1: State the corresponding Z-score value for YOUR x value_ 2: State what YOUR z-score means_
