)Voc pode sustentar a afirmao de que a precipitao mdia das nuvens semeadas excede 20.771 acres-ps, ou diferente desse valor? Use = 0.01e suponha que a precipitao pluviomtrica seja normalmente distribuda.

Par isso, obtenha o nvel descritivo (p-valor), que pode ser:

p=P(Xx)

para testar as hipteses:

{H0 :=20.771

H1 :20.771

(hiptese nula );

(hiptese alternativa ).

Ou seja, obtenha a probabilidade de se obter valores mais extremos do queX =x

p=

Resposta para parte 2

c) Deve-se rejeitar a hipteses nula ao nvel de 1%?

a.Deve-se rejeitar a hiptese nula a esse nvel

b.No se rejeita a hiptese nula a esse nvel
