Answer
Explanation:
Step1: Analyze quantitative - qualitative data
Quantitative data is numerical and can be measured or counted in a meaningful way. The data here is about the number of pets, but it's presented in categories (0 pets, 1 pet, etc.), so it's categorical (qualitative) data, not quantitative. So the first statement is false.
Step2: Calculate percentages of non - pet owners
Percentage of boys who do not own a pet: $\frac{8}{15}\times100%\approx53.3%$. Percentage of girls who do not own a pet: $\frac{7}{20}\times100% = 35%$. So the second statement is false.
Step3: Check number of girls with 2 or more pets
The number of girls with 2 pets is 5 and with more than 2 pets is 2. The total number of girls who own 2 or more pets is $5 + 2=7\neq2$. So the third statement is false.
Step4: Compare number of girls with and without pets
Number of girls who do not own a pet is 7. Number of girls who own a pet is $6 + 5+2=13$. Since $7<13$, more girls own a pet than do not own a pet. So the fourth statement is false.
However, if we assume there is a mis - typing in the analysis of the fourth statement and we re - calculate: Number of girls who do not own a pet is 7. Number of girls who own a pet is $6+5 + 2=13$. But if we consider the correct logic for the fourth statement as "More girls do not own a pet than own 1 pet": Number of girls who do not own a pet is 7. Number of girls who own 1 pet is 6. So the statement "More girls do not own a pet than own 1 pet" is True.
