For a Distribution of Scores,X = 40 Corresponds to a Z-Score

question 73

Short Answer

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.)
