- In a normal distribution of = 50 and SD = 7:
- What is the score at the 75th percentile (hint: on the table, find the z-score at .750 and change back to a raw score)?
- Find the percent of cases scoring above 55.
- Between what scores to the middle 25% of the cases lie?
- Beyond what scores do the most extreme cases lie?
