In​ psychology, it has been suggested that the number S of nonsense syllables that a person can repeat consecutively depends on his or her IQ score I according to the equation S=Square root 2I−9. Use this relationship to estimate the IQ of a person who can repeat 12 nonsense syllables consecutively.
