the survey represents quantitative data.
there is a greater percentage of girls who do not own a pet than boys who do not own a pet.
the total number of girls who own 2 or more pets is 2.
more girls do not own a pet than do own a pet.

Explanation:

Step1: Analyze the first option

Quantitative data is numerical. The data about number of pets is numerical. So, the survey represents quantitative data.

Step2: Analyze the second option

Percentage of boys who do not own a pet: \(\frac{8}{15}\approx0.533\) (or \(53.3\%\)). Percentage of girls who do not own a pet: \(\frac{7}{20} = 0.35\) (or \(35\%\)). So, this option is false.

Step3: Analyze the third option

Total number of girls who own 2 or more pets: \(5 + 2=7
eq2\). So, this option is false.

Step4: Analyze the fourth option

Number of girls who own a pet: \(6 + 5+2=13\). Number of girls who do not own a pet: \(7\). \(13>7\). So, this option is false.

Answer:

The survey represents quantitative data.
