@racastilho I'm mad late.. But one has to know how to differentiate between type I and II errors.

[racastilho]

There are two things that really confuse me:

1) If the result of the testing is either to accept or reject the null hypothesis, why should the alternative hypothesis matter? The conclusion is always in relation to the null hypothesis, not?

2) Given the the mu is real number, the chance of it being EXACTLY any number is infinitesimal... I think one should always reject the hypothesis that mu is any given EXACT number (unless we know the population, of course)!

If someone can clarify...Thanks!
