<h3>What is a representative sample?</h3>
Representative samples are little amounts or components that are a part of a bigger group or organization. It shares the same characteristics as the bigger population it represents.
Consider a company in Germany's Bavaria that is going to launch a new service or product. It would be difficult for the company to poll every Bavarian to determine how they felt about the launch. As an alternative, researchers can compile a small sample from various locations in Bavaria that will serve as a representative sample of the local populace. After that, a survey will be given to the respondents to gather their comments on the good or service. A "representative sample" is the term used to describe this selection of Bavarian individuals.

Answer:
d. 133.
Explanation:
IQ otherwise known as Intelligent Quotient, is a measure of intelligence, which is applied by using ratio of mental age to physical or chronological age, then multiply by 100.
Hence, a child of 9year old had a mental age of 12 year old, (which means, performing on the test meant for an average 12 year old) the child is then assigned IQ of 12/9 * 100 which equals to IQ of 133.
Therefore, a 9-year-old who responded to the original Stanford-Binet with the proficiency of an average 12-year-old was said to have an IQ of 133.
