A- A distribution of scores has μ = 85. The z-score for X = 105 is computed and a value of z = -1.00. Regardless of the value of the standard deviation, why must this z-score be incorrect? B- For a population with μ = 62 and σ = 8, 1- Find the z-scores that correspond to each of the following X-values: X = 70 X = 46 X = 82 X = 58 X = 62 X = 56 2- Find the raw score (X) for each of the following z-scores: z = -2.50 z = -0.25 z = 1.25 z = 2.25 z = -1.00 z = 0.75

Question
A- A distribution of scores has μ = 85. The z-score for X = 105 is computed and a value of z = -1.00. Regardless of the value of the standard deviation, why must this z-score be incorrect?
B- For a population with μ = 62 and σ = 8,
1- Find the z-scores that correspond to each of the following X-values:
X = 70 X = 46 X = 82
X = 58 X = 62 X = 56
2- Find the raw score (X) for each of the following z-scores:
z = -2.50 z = -0.25 z = 1.25
z = 2.25 z = -1.00 z = 0.75
