Quizplus · Accepted Answer

José's score on the Stanford-Binet test suggests that his mental age (9 years) is higher than his chronological age (7 years). This means that his IQ would be calculated as (mental age / chronological age) x 100, which gives us (9/7) x 100 = 128. According to the IQ classification system, a score of 128 falls in the above average range, indicating that José has a higher level of intelligence than most children his age. Therefore, option A is the correct answer.
