Respuesta:
A) media aritmética : 2.86
Me : 3
Mo : 2
B) media aritmética : 2.53
Me : 2
Explicación paso a paso:
A)
[tex]x = \frac{5 + 5 + 5 + 4 + 3 + 4 + 3 + 2 + 2 + 1 + 1 + 1 + 2 + 2 + 3}{15} \\ = \frac{43}{15} \\ = 2.86[/tex]
Me = 1, 1, 1, 2, 2, 2, 2, 3, 3, 3, 4, 4, 5, 5, 5
Me = 3
Mo = 2
B)
[tex]x = \frac{2 + 1 + 1 + 2 + 2 + 3 + 2 + 4 + 5 + 5 + 4 + 2 + 2 + 1 + 2}{15} \\ = \frac{38}{15} \\ = 2.53[/tex]
Me = 1, 1, 1, 2, 2, 2, 2, 2, 2, 2, 3, 4, 4, 5, 5
Me = 2
