The true statements are:
- 44/85 of the student surveyed do not ride the bus to school
- About 32% of the students are in the 9th grade
The false statements are:
- 64% of the students are 11th graders
- 134/150 of the students surveyed are in 9th or 10th grade
How to interpret the two-way frequency table
The students that do not ride bus to school
From the table, 220 students do not ride bus to school.
So, the proportion of students that do not ride bus to school is:
[tex]p=\frac{220}{425}[/tex]
Simplify
[tex]p=\frac{44}{85}[/tex]
Hence, this statement is true
The 9th graders
From the table, 134 students are 9th graders
So, the proportion of students that are 9th graders is:
[tex]p=\frac{134}{425}[/tex]
Divide
[tex]p=0.315[/tex]
Approximate, and represent as percentage
[tex]p=32\%[/tex]
Hence, this statement is true
The 11th graders
From the table, 141 students are 11th graders
So, the proportion of students that are 11th graders is:
[tex]p=\frac{141}{425}[/tex]
Divide
[tex]p=0.331[/tex]
Approximate, and represent as percentage
[tex]p=33\%[/tex]
Hence, this statement is false
The 9th or 10th graders
From the table, 134 + 150 students are 9th or 10th graders
So, the proportion of students that are 11th graders is:
[tex]p=\frac{134 + 150}{425}[/tex]
[tex]p=\frac{284}{425}[/tex]
Hence, this statement is false
