For a set of observations with a mean of 65 and a standard deviation of 12, nd the zscore for each of the following raw scores: X=80 X=56 X=92 X=42 X=73 X=48 2. For a set of observations with a mean of 36 and a standard deviation of 9, nd the raw score for each of the following zscores: z = 1.00 z = 0.25 z = 1.50 z = 0.50 z = 1.25 z = 2.50 3. A set of observations with a mean of 64 and a standard deviation of 12 is transformed into a standardized distribution with a mean of 100 and stande deviation of 20. Find the new, standardized score for each of the following values from the original set of observations: (a) X=61 (b) X=70 (c) X=85 (d) X=94 4. A set of observations has a standard deviation of a = 6, and a score of X = 42 corresponds to a z = 0.50. What is the mean u of the set of observations? 5. A set of observations has a mean of ,u = 53, and a score of X = 59 corresponds to z = 2.00. What is the standard deviation 0"
