H_0:\mu=380\\\\H_a: \mu>380

Step-by-step explanation:

The alternative hypothesis shows the claim of the researchers. In this case, that the new type of fertilizer significantly increase the actual yield with the old fertilizer:

H_a: \mu>380

The null hypothesis is the hypothesis to be <em>nullified</em>, so it states that the claim is not true and the yield is the same (or, at least, not significantly higher) as with the old fertilizer:

H_0: \mu=380
