Step-by-step explanation:
Hello!
The objective of this experiment is to test if a new feed + additive generates a better production of milk in cows. For this, the owner selects 13 cows and randomly separates them into two groups.
Group 1 has 8 cows that receive the new feed + additive.
Group 2 has 5 cows that were fed with the old feed.
After two weeks of feeding the animals with the different feeds, the production of milk of each group was recorded so that they can be compared.
Since you have two separate groups to wich at random two different treatments were applied and later the variable was measured, these two samples/groups are independent and the proper test to compare the population means of the milk production in both groups is a pooled t.
I hope this helps!

Answer: -3g - 4
(-2g + 7) - (g + 11)

<h2>The Third table of ordered pairs represents a proportional relationship.
</h2>
Explanation:
A proportional relationship is defined as the relationship between two quantities where one is directly proportional to another with a proportionality constant.
For example, y = ax
Here a is the proportionality constant.
This expression shows that y varies directly as x varies.
From the tables mentioned in the below attachment, we can easily say that "Table 3" has the ordered pairs which represents proportional relationship.
Table 3 defines y is directly proportional to x with proportionality constant 
.
