The correct Answer is:
To solve the problem, we need to determine the range of IQ scores for about 50 of the children in the sample based on the provided statistics. ### Step-by-Step Solution: 1. **Understand the Quartiles**: - The first quartile (Q1) is given as 84. This means that 25% of the children have IQ scores below 84. - The third quartile (Q3) is given as 110. This means that 75% of the children have IQ scores below 110. 2. **Identify the Range of the Middle 50%**: - The middle 50% of the data is represented by the interquartile range, which is the range between Q1 and Q3. - Since Q1 is 84 and Q3 is 110, the range of IQ scores for the middle 50% of the children will be from Q1 to Q3. 3. **Calculate the Range**: - The range of IQ scores for the middle 50% of children is from 84 to 110. - Therefore, about 50 of the children in this sample have IQ scores that fall between 84 and 110. ### Final Answer: About 50 of the children in this sample have IQ scores that are between **84 and 110**. ---
