Explanation:

Step1: Calcular porcentaje de residentes de LA que tienen auto

$\frac{3251}{4120}\times100\approx78.91\%$

Step2: Calcular porcentaje de residentes de NYC que tienen auto

$\frac{1478}{7660}\times100\approx19.29\%$

Step3: Analizar opciones

  • La encuesta es de datos categóricos (tiene auto o no), no cuantitativos, así que la opción A está incorrecta.
  • El total de personas que tienen auto es 4729, no 4120, así que la opción C está incorrecta.
  • El total de personas que no tienen auto es 7051 y el total de personas que tienen auto es 4729, entonces menos personas tienen auto que no la tienen, la opción D está incorrecta.
  • Como $78.91\%>19.29\%$, la opción B es verdadera.

Answer:

B. There is a greater percentage of LA residents who own a car than NYC residents who do.
