tanford Binet IQ scores have a mean of 100 and a standard deviation of 16. Albert Einstein reportedly had an IQ of 160. a. Convert Einstein's IQ score to a z-score. z = nothing b. Is Einstein's IQ unusual? A. Yes, becuase the z-score is greater than 2. B. No, because the z-score is negative. C. No, because the z-score is less than 2. D. Yes, because the z-score is greater than 1.
