Final answer:
Bill's IQ, calculated by dividing his mental age by his chronological age and multiplying by 100, is approximately 133. This score is considered above average and within the range typically associated with gifted children.
Explanation:
The question is asking to determine Bill's Intelligence Quotient or IQ. IQ is calculated by dividing the mental age by the chronological age, then multiplying the result by 100. In this case, Bill's mental age is 8 years old, while his chronological age is 6 years old. So, the IQ would be (8/6)*100 = 133.33. This means that Bill's IQ is approximately 133, which is well above the average IQ of 85-115 and even exceeds the mark of 130 that is typically used to indicate 'giftedness' in children.
