Respuesta:
[tex]0.65[/tex] ; la correcta es la opción C )
Explicación paso a paso:
Buscamos f 4.
[tex]f1 +f2+f3+f4 = n[/tex]
[tex]4+1+6+f4 = 20[/tex]
[tex]11+f4 = 20[/tex]
[tex]f4 = 20-11[/tex]
[tex]f4 = 9[/tex]
[tex]h_{1} = \frac{f1}{n} =\frac{4}{20} = 0.2[/tex]
[tex]h_{4} = \frac{f4}{n} = \frac{9}{20} =0.45[/tex]
[tex]Luego: h_{1} + h_{4} = 0.2+0.45 = 0.65[/tex]
