Answer #2

To test whether cloud seeding increases the average annual rainfall in an area which usually has an average annual rainfall of 20 cm, we define the null and alternative hypotheses as follows, where μ represents the average rainfall after cloud seeding.

H0: µ ≤ 20 (i.e. average rainfall does not increase after cloud seeding)

H1: µ > 20 (i.e. average rainfall increases after cloud seeding

My test will be one sided.

The critical value is in the right tail.

So, this is a right tail test.
