Answer:

Null Hypothesis, $H_0$ : $\mu$ $\leq$ 120 grams

Alternate Hypothesis, $H_A$ : $\mu$ > 120 grams

Step-by-step explanation:

We are given that researchers captured brown tree snakes on Guam's Andersen Air Force Base, and a random sample of 250 of these snakes were weighed.

The researchers want to perform a hypothesis test to see if the mean weight of a brown tree snake in Guam is significantly greater than 120 grams.

Let $\mu$ = mean weight of a brown tree snake in Guam.

So, Null Hypothesis, $H_0$ : $\mu$ $\leq$ 120 grams

Alternate Hypothesis, $H_A$ : $\mu$ > 120 grams

Here, null hypothesis states that the mean weight of a brown tree snake in Guam is smaller than or equal to 120 grams.

On the other hand, alternate hypothesis states that the mean weight of a brown tree snake in Guam is significantly greater than 120 grams.

So, this would be the appropriate null and the alternative hypothesis to test this claim.
