Brown tree snakes are an invasive species causing huge environmental and financial damage in Guam. 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.
Set up the appropriate null and alternate hypotheses for the test.

Answer :

Answer:

Null Hypothesis, [tex]H_0[/tex] : [tex]\mu[/tex] [tex]\leq[/tex] 120 grams

Alternate Hypothesis, [tex]H_A[/tex] : [tex]\mu[/tex] > 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 [tex]\mu[/tex] = mean weight of a brown tree snake in Guam.

So, Null Hypothesis, [tex]H_0[/tex] : [tex]\mu[/tex] [tex]\leq[/tex] 120 grams

Alternate Hypothesis, [tex]H_A[/tex] : [tex]\mu[/tex] > 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.
