The Mental Development Index (MDI) is a measure used in observing infants over time. Suppose MDI scores are approximately normally distributed with a mean of 105 and a standard deviation of 15. Which of the following is a true statement? An infant with a MDI score of 135 would be farther away from the mean than an infant with a standardized MDI score of -2.25 An infant with a MDI score of 120 would be at the 84th percentile. An infant with a MDI score of 125 would be at a higher percentile than an infant with a Z-score of 2 Approximately 84% of all MDI scores are less than 90 Approximately 95% of all MDI scores are between 90 and 120.
