4) Stanford Binet IQ scores have a mean of 100 and a standard deviation of 16. IQ scores are roughly normally distributed.

(a) Sketch the normal curve, and label everything appropriately using the Empirical Rule, z-scores, and data values with the appropriate IQ scores.

(b) If a person's IQ has a z-score of −0.3, then explain what that tells you about how the person's IQ

compares to other people's IQ.

(c) A person has an IQ of 82. Find the z-score for this IQ score, and explain exactly what it tells you about how this person's IQ compares to other people.

(d) To have an "unusually high" IQ, a person would need to have an IQ with a z-score of 2 or more. How high would a person's IQ need to be to be considered "unusually high?" Show your work.

(e) Albert Einstein had an estimate IQ of 160. Convert Einstein’s IQ score to a z-score (show your work). What does the z-score tell us about Albert Einstein’s IQ? Is it unusual?
