Question

a student creates a segmented bar graph from the two - way table to compare lunch choices by grade.
which of the following claims is most supported by the segmented bar graph?
the total number of students surveyed was equal for both grades.
grade 7 students are more likely to bring lunch than grade 8 students.

Explanation:

Step1: Analyze the first option

The total number of students surveyed for Grade 7 is \(28\) (\(10 + 18\)) and for Grade 8 is \(26\) (\(14+12\)). So, the total number of students surveyed for both grades is not equal.

Step2: Analyze the second option

The percentage of Grade 7 students who brought lunch is \(64.3\%\) (\(\frac{18}{28}\)) and for Grade 8 students who brought lunch is \(46.2\%\) (\(\frac{12}{26}\)). Since \(64.3\%>46.2\%\), Grade 7 students are more likely to bring lunch than Grade 8 students.

Answer:

Grade 7 students are more likely to bring lunch than Grade 8 students.
