Uma determinada região apresentou, nos últimos 5 anos, os seguintes valores para a precipitação pluviométrica, medida em mm: 31,0 34,0 28,0 29,0 e 28,0. Com base nos dados, assinale a alternativa que apresenta à média, mediana, moda, respectivamente:
a.30,0 28,0 28,0.
b.30,0 29,0 28,0.
c.28,0 30,0 29,0.
d.30,0 28,0 30,0.
e.29,0 28,0 28,0.

Alternativa correta: "b"
média:
31,0 + 34,0 + 28,0 + 29,0 + 28,0 = 150 / 5 = 30,0
mediana:
28,0----28,0----29,0----31,0----34,0 = 29,0
moda:
31,0 - 34,0 - 28,0 - 29,0 - 28,0 = 28,0
média:
31,0 + 34,0 + 28,0 + 29,0 + 28,0 = 150 / 5 = 30,0
mediana:
28,0----28,0----29,0----31,0----34,0 = 29,0
moda:
31,0 - 34,0 - 28,0 - 29,0 - 28,0 = 28,0
