The 10-year-olds box plot has a median distance of around 30 inches, while the 15-year-olds box plot has a median distance of around 40 inches.
Therefore, the difference between the two medians is 10 inches (40 inches - 30 inches = 10 inches).
Additionally, the box plot for the 15-year-olds has more spread because the whiskers are longer and the range of distances is larger compared to the box plot for the 10-year-olds.
These two box plots show the distances of a standing jump, in inches, for a random sample of 10-year-olds and a random sample of 15-year-olds. Use these box plots to answer the questions below. (2 points) The difference between the two medians is . The box plot for the -year-olds has more spread.

is this right
Yes, that is correct. The difference between the two medians is 10 inches (40 inches - 30 inches = 10 inches) and the box plot for the 15-year-olds does indeed have more spread compared to the box plot for the 10-year-olds based on the length of the whiskers and the range of distances shown.
The box plots above show us how far a group of students jumped. What can you infer about the differences between the two age groups
Based on the box plots showing the distances of a standing jump for a random sample of 10-year-olds and a random sample of 15-year-olds, we can infer the following differences between the two age groups:
1. The median jump distance for the 15-year-olds is higher than the median jump distance for the 10-year-olds, indicating that, on average, the 15-year-olds can jump farther than the 10-year-olds.
2. The 15-year-olds sample has more variability in jump distances than the 10-year-olds sample, as evidenced by the longer whiskers and the larger range of distances shown in the box plot for the 15-year-olds. This suggests that there is more diversity in jumping abilities among the 15-year-olds compared to the 10-year-olds.
3. The interquartile range (IQR) for the 15-year-olds appears to be wider than the IQR for the 10-year-olds, indicating that there is a greater spread of jump distances within the 15-year-olds group compared to the 10-year-olds group.
Overall, these inferences suggest that, on average, 15-year-olds have a higher jump distance and more variability in jump distances compared to 10-year-olds.
