Please anwser by hand!

(Bonus -- By-Hand) Dr. Greg Garman, Director of the VCU Rice Rivers Center, has studied Atlantic Sturgeon extensively during his career. Suppose that he has
determined a linear model that can be used to predict the weight of an Atlantic Sturgeon based upon its length: y = a + ₁x₁ + ε. Upon further study, Dr. Garman has
noticed that the relationship between weight and length for these fish is different for males than for females. Thus, he'd like to modify his linear model to be able to fully
take into account the sex of the fish. Please list the complete modified model that will fully take into account the sex of the fish, and then be sure to explain each of the
terms of the new model (including all terms from the original model and any new terms added to modify the model).
Original Model: y = a +
₁x₁ + ε
Description of original terms:
y:
X1:
α:
B₁:
E:
New Complete Modified Model: y = a + ₁x₁ +.
Description of new terms:
+ ε
[Hint: When writing-up your answer, first describe what each of the five terms from the original model mean specific to this scenario. Then, write out the complete modified model (copy
from above and fill-in the new terms in the blank space) and describe each of the additional terms that you added into the blank space (be sure to state what they mean specific to this
scenario).]
