Final answer:
The correct dataset that matches the bar chart values for the number of students traveling to different schools is {7, 7, 7, 7, 7, 7, 7, 5, 5, 5, 5, 5, 4, 4, 4, 4}.
Step-by-step explanation:
The question asks us to identify the dataset represented in a bar chart that summarizes the number of students needing to travel to elementary, middle, and high school, with values of 7, 5, and 4, respectively.
After analyzing the provided datasets, the correct dataset that matches the values on the bar chart is the second option: {7, 7, 7, 7, 7, 7, 7, 5, 5, 5, 5, 5, 4, 4, 4, 4}. This dataset corresponds to 7 students for the elementary school (ages 5-10), 5 students for the middle school (ages 11-13), and 4 students for the high school (ages 14-18).
The data set represented in the bar chart is: {7, 7, 7, 7, 7, 7, 7, 5, 5, 5, 5, 5, 4, 4, 4, 4}. This is because the bar chart shows that there are 7 students in the Elementary School age group, 5 students in the Middle School age group, and 4 students in the High School age group.
