Question

a grocery store recorded how many customers visited the store each day.
grocery store customers
day number of customers
thursday 85
friday 87
saturday 89
sunday 75
monday 99
what is the median of the numbers?

Explanation:

Step1: Ordenar los números

Ordenamos los números de clientes: \(75\), \(85\), \(87\), \(89\), \(99\)

Step2: Encontrar el término central

Como hay \(n = 5\) números (impar), el índice del término central es \(\frac{n + 1}{2}=\frac{5+1}{2}=3\)
El tercer término de la lista ordenada \(75\), \(85\), \(87\), \(89\), \(99\) es \(87\)

Answer:

\(87\)
