Re: The reason of a notation (The unnecessary explanation).

*** In "Never, Bob Ling, NEVER", Aug. 26, 2006, 4:37
AM, for instance, you defined the null and
alternative hypotheses as

Ho: p1 = p2 and H1: p1 =/p2.

Therefore, if we are given that p1 = 0.571 and p2 =
0.500, that information is sufficient for us to know
that H1 is true.

NOY AT ALL

Suppose thé following problem :

*** Find if, concerning the observed success
frequencies in two samples
_______________p1 = 0.571
_______________p2 = 0.500,
it can be stated H0 : p1= p2 (H1 = p1 not equal:
p2) at the 95% confidence level ***

DO TRY

_____________licas (Luis A. Afonso)


Since you told me what p1 and p2 are, I can state with 100% confidence that H1 is true.
