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.

<u><em>Let </em></u>\mu<u><em> = mean weight of a brown tree snake in Guam.</em></u>

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

Alternate Hypothesis, H_A : \mu > 120 grams

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

On the other hand, <u>alternate hypothesis states that</u> 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.
