Final answer:
The correct option is b) 100.
Dominque would be considered to have average intelligence with an IQ test score of 100, as this is the standard average score set on most IQ tests.
Step-by-step explanation:
Dominique's IQ test score of 100 is indicative of average intelligence, as on most modern IQ tests, the average score is set at 100. This standardization allows for a comparative assessment of an individual's cognitive abilities within the population. With a standard deviation of 15 points, scores are distributed according to a bell curve, or normal distribution.
Scores within one standard deviation above and below the mean, in this case, between 85 and 115, are categorized as average. About 68% of the population falls within this range, reflecting the typical distribution of intelligence in a given population.
An IQ score of 120 is considered above average, indicating cognitive abilities that surpass the majority of the population. This score falls approximately one standard deviation above the mean. Conversely, a score of 140 is indicative of a superior level of intelligence, placing an individual significantly above the average and in the top echelons of intellectual ability.
On the lower end, a score of 85 would be considered below average but still within the majority of the population. It falls within one standard deviation below the mean. It's important to note that IQ scores are relative measures, providing insights into an individual's standing within a particular population. They are not absolute measures of intelligence and should be interpreted with consideration of factors such as cultural bias and the limitations of standardized testing.
