The Welcher Intelligence Test Scale is composed of a number of subtests. On one subtest, the raw scores have a mean of 45 and a standard deviation of 7. Assuming these raw scores form a normal distribution: What number represents the 65th percentile (what number separates the lower 65% of the distribution)? = What number represents the 90th percentile? = What is the percentage of getting a raw score between 28 and 38? What is the percentage of getting a raw score between 41 and 44?
