Answer:
Null Hypothesis, :
120 grams
Alternate Hypothesis, :
> 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><u><em> = mean weight of a brown tree snake in Guam.</em></u>
So, Null Hypothesis, :
120 grams
Alternate Hypothesis, :
> 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.
