Post by: becca29 on Mar 19, 2018 For a distribution of scores, X = 40 corresponds to a z-score of z = 1.00, and X = 42 corresponds to a z-score of z = 0.50 . What are the values for the mean and standard deviation for the distribution? (Hint: sketch a distribution and locate each of the z-score positions.)
What will be an ideal response? Question 2 For a population with = 40 and = 8, find the z-score corresponding to each of the following X values: 42, 52, 36, 32 What will be an ideal response? Question 3 Explain what is measured by the sign of a z-score and what is measured by its numerical value. What will be an ideal response?
