Q1) Distribution with mean of  m =38 and standard deviation of s=20 is being transformed into standardized distribution with m =50 and s=10. Determine new, standardized score for each of following values from original population.

a) X=48 

b) X=40

c) X=30 

d) X=18

 For population with mean of m = 100 and standard deviation of s = 10.

a) Determine z-scores for each of following X values.

       X = 105      X = 120       X = 130

       X = 90        X = 85         X = 60

b) Determine score (X values) that corresponds to each of following z-scores.

       z = -1.00      z = -0.50       z = 2.00

       z = 0.70       z = 1.50         z = -1.50
