as part of a survey, a group of people were asked to name their preferred method of viewing television shows. their responses are shown in the table.\n\n| viewing method | number of people | key for bar graph |\n| ---- | ---- | ---- |\n| live | 8 | |\n| recorded | 9 | |\n| on demand | 3 | |\n| online streaming | 5 | |\n\nwhich percentage bar graph best represents the data?

Answer

Explanation:

Step1: Calcular el total de personas

$8 + 9+3 + 5=25$

Step2: Calcular el porcentaje para cada método de visualización

Live

$\frac{8}{25}\times100 = 32%$

Recorded

$\frac{9}{25}\times100 = 36%$

On - demand

$\frac{3}{25}\times100 = 12%$

Online streaming

$\frac{5}{25}\times100 = 20%$

Step3: Analizar cada gráfico de barras de porcentajes

En el gráfico A, los porcentajes no coinciden con los calculados.
En el gráfico B, los porcentajes no coinciden con los calculados.
En el gráfico C, los porcentajes ($32%,36%,12%,20%$) coinciden con los calculados para Live, Recorded, On - demand y Online streaming respectivamente.
En el gráfico D, los porcentajes no coinciden con los calculados.
