Question

students from school a and school b were asked whether they watch tv or use the internet after finishing their homework. the venn diagram and the two - way table show the results from the two surveys. which statement is true? more students do both activities at a than at b. more students watch tv at b than at a. more students do neither activity at b than at a. more students were surveyed at a than at b.

Explanation:

Step1: Calcular estudiantes que no hacen ninguna actividad en A

En el diagrama de Venn de la Escuela A, los estudiantes que no hacen ni看电视 ni usar Internet son 0 (ya que no hay nada fuera de los círculos).

Step2: Calcular estudiantes que no hacen ninguna actividad en B

En la tabla de dos - vías de la Escuela B, los estudiantes que no usan Internet y no ven televisión son 4.

Step3: Comparar

Como 4 > 0, más estudiantes no hacen ninguna actividad en B que en A.

Answer:

C. More students do neither activity at B than at A.
