from unit 1, lesson 3 the histogram represents the distribution of the number of seconds it took for each of 50 students to find the answer to a trivia question using the internet. which interval contains the median? a 0 to 5 seconds b 5 to 10 seconds c 10 to 15 seconds d 15 to 20 seconds learning target + i can arrange data sets in order of variability, given graphic representations

Answer

Explanation:

Step1: Calcular el número total de datos

Tenemos 50 estudiantes, es decir, 50 datos. El mediana para un conjunto de 50 datos (número par de datos) está dada por el promedio del 25º y 26º dato ordenados.

Step2: Sumar frecuencias acumulativas

Sumando las frecuencias acumulativas de las clases:

  • Clase 0 - 5 segundos: Frecuencia acumulativa 5
  • Clase 5 - 10 segundos: Frecuencia acumulativa 5 + 10=15
  • Clase 10 - 15 segundos: Frecuencia acumulativa 15+15 = 30 Los 25º y 26º datos se encuentran en la clase 10 - 15 segundos.

Answer:

C. 10 a 15 segundos
