A negatively skewed distribution has = 60, = 10. If this entire distribution is transformed into z-scores, describe the shape, mean, and standard deviation for the resulting distribution of z-scores.
A distribution of scores has a mean of = 500. In this distribution, a score of X = 550 is located 50 points above the mean.
1. Assume the standard deviation is = 25. Sketch the distribution and locate the position of X = 550. What is the z-score corresponding to X = 550 in this distribution?
2. Assume the standard deviation is = 100. Sketch the distribution and locate the position of X = 550. What is the z-score corresponding to X = 550 in this distribution?
A distribution of scores has = 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?
