When the StanfordâBinet IQ test came into use in 1932, it was adjusted so that scores for each age group of children followed roughly the Normal distribution with mean 100 and standard deviation 15 . The test is readjusted from time to time to keep the mean at 100 . If presentâday American children took the 1932 StanfordâBinet test, their mean score would be about 120 . The reasons for the increase in IQ over time are not known but probably include better childhood nutrition and more experience in taking tests. IQ scores above 130 are often called "very superior." What percentage of children had very superior scores in 1932? (Enter your answer rounded to two decimal places.)
