To analyze the box plot, we need to understand its components. The box represents the interquartile range (IQR), which is the range between the first quartile (Q1) and the third quartile (Q3), containing the middle 50% of the data. The line inside the box indicates the median age. In this case, the box extends from 10 to 12, suggesting that the middle 50% of the children's ages fall between these values. The median age can be inferred to be around 11 years old. Since the box plot does not show whiskers or outliers, we cannot determine the full range of ages or the presence of outliers. The statement that half of the children were between 6 and 9 years old is true based on the information provided, while the other statements cannot be confirmed from the box plot.
