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.
For this case we have:
Let:
- s: Profit from sales in a given week
- e: Seller's weekly profit
Where "c" represents the commission.
The commission on sales can be observed with the application of a rule of three:
s ---------> 100%
c ---------> 4%
Thus, e is given by:
