True or False

1. Two event A and B are independent iff P(A|B) = P(A).

2. For a specific population, the value of a parameter may change.

3. The sampling distribution of the sample mean, X, is always given by a normal curve.

4. Suppose a 95% CI for µ is given by (-2.38, -1.22). Then, based on the CI for µ, a valid conclusion would be µ < 0.
