1 The location of the rejection region for the null hypothes

1. The location of the rejection region for the null hypothesis is determined by:

a) the sign in the null hypothesis

b) the sign in the alternative hypothesis

c) the size of

d) the size of n

2. When a null hypothesis cannot be rejected, we conclude that:

a) the null hypothesis is true

b) the null hypothesis may be true

c) the alternative hypothesis is true

d) the alternative hypothesis may be true

Solution

1) b) the sign in the alternative hypothesis

and also the value of alpha, but (b) is more important.

2) b) the null hypothesis may be true

and also (d) but (b) is more important.
