jenny watched the cashier scan the 7 items in her shopping cart. the scanned prices were: $6.00 $6.00 $6.00 $8.00 $5.00 $2.00 $7.00 what was the median price of the items?
Step1: Ordenar los precios
Ordenamos los precios de menor a mayor: \( \$2.00,\$5.00,\$5.00,\$6.00,\$6.00,\$6.00,\$7.00,\$8.00 \)
Step2: Encontrar el valor central
Como hay \( n = 7 \) valores (número impar), la mediana es el valor en la posición \( \frac{n + 1}{2}=\frac{7+ 1}{2}=4 \)
