Sumar y dividir los datos del inciso a

\[

$$\begin{aligned} &\text{Datos: } 5, 9, 5, 6, 9, 8, 7, 4, 5, 9 \\ &N = 10 \\ &\text{Suma} = 5 + 9 + 5 + 6 + 9 + 8 + 7 + 4 + 5 + 9 = 67 \\ &\text{Media} = \frac{67}{10} = 6.7 \end{aligned}$$

\]

Sumar y dividir los datos del inciso b

\[

$$\begin{aligned} &\text{Datos: } 57, 65, 83, 69, 93, 57, 63, 92, 94, 73, 89 \\ &N = 11 \\ &\text{Suma} = 57 + 65 + 83 + 69 + 93 + 57 + 63 + 92 + 94 + 73 + 89 = 832 \\ &\text{Media} = \frac{832}{11} \approx 75.64 \end{aligned}$$

\]

Identificar el valor más frecuente en el ejercicio 3

\[

$$\begin{aligned} &\text{Datos: } 27, 22, 29, 27, 82, 20, 28, 29, 70 \\ &\text{Frecuencias: } 27 ightarrow 2,\ 29 ightarrow 2,\ 22 ightarrow 1,\ 82 ightarrow 1,\ 20 ightarrow 1,\ 28 ightarrow 1,\ 70 ightarrow 1 \\ &\text{Modas} = 27 \text{ y } 29 \end{aligned}$$
