Question

the following table shows the data collected from students in grades 3 and 4 in an elementary school about their favorite types of pets. which of the following statements is supported by the table? a dogs were the type of pet chosen most often by the students at the elementary school. b there were more students surveyed in grade 3 than in grade 4. c the percentage of students who chose cats as their favorite pet was 60%. d the percentage of students in grade 3 who chose dogs as their favorite pet was 55%.

Explanation:

Step1: Analyze option A

The total number of students who chose dogs is 110, which is the highest among all pet - types. So dogs were the type of pet chosen most often by the students at the elementary school.

Step2: Analyze option B

Number of grade 3 students surveyed = 105, number of grade 4 students surveyed = 110. There were not more students surveyed in grade 3 than in grade 4.

Step3: Analyze option C

In grade 3, number of students who chose cats = 25, total number of grade 3 students = 105. Percentage of grade 3 students who chose cats is $\frac{25}{105}\times100\%\approx23.8\%$, not 60%.

Step4: Analyze option D

In grade 3, number of students who chose dogs = 60, total number of grade 3 students = 105. Percentage of grade 3 students who chose dogs is $\frac{60}{105}\times100\%\approx57.1\%$, not 55%.

Answer:

A. Dogs were the type of pet chosen most often by the students at the elementary school.
