Which of the following statements is supported by the table?

Steps to Solve

1. Calculate Total Pet Choices for Each Type

   We need to sum the total number of students who chose each type of pet from the table.

   • Cats: $25 + 35 = 60$
   • Dogs: $60 + 50 = 110$
   • Birds: $5 + 15 = 20$
   • Other: $15 + 10 = 25$

2. Analyze Statement A: Dogs were the type of pet chosen most often

   Compare the total for each pet type:

   • Cats: 60
   • Dogs: 110
   • Birds: 20
   • Other: 25

   Since $110 > 60$, the statement is TRUE.

3. Analyze Statement B: More students surveyed in grade 3 than in grade 4

   Compare the total students surveyed:

   • Grade 3: 105
   • Grade 4: 110

   Since $105 < 110$, this statement is FALSE.

4. Analyze Statement C: Percentage of students who chose cats as their favorite pet was 60%

   Calculate the percentage: [ \text{Percentage} = \frac{\text{Total Cats}}{\text{Total Students}} \times 100 = \frac{60}{215} \times 100 \approx 27.91% ] This statement is FALSE.

5. Analyze Statement D: Percentage of students in grade 3 who chose dogs as their favorite pet was 55%

   Calculate the percentage specifically for grade 3: [ \text{Percentage} = \frac{60}{105} \times 100 \approx 57.14% ] This statement is FALSE.

6. Analyze Statement E: Birds were the type of pet chosen least often by students in grade 4

   For grade 4, we have:

   • Birds: 15
   • Compare with other pets:
     • Cats: 35
     • Dogs: 50
     • Other: 10

   Since $15 > 10$, but less than both Cats and Dogs, this statement is TRUE. However, it is not the least chosen overall, as Other has only 10.
