Answer:
Option C is the correct option.
In other words, the quadratic regression best fits the data set, as it gets very much close to the data values given in the data table.
The graph of the equation is also attached.
Step-by-step explanation:
x y
3 470
4 416
5 403
Analyzing Option A:
Considering the equation
From (3, 470), putting x = 3
From (4, 470), putting x = 4
From (5, 403), putting x = 5
Analyzing Option B:
From (3, 470), putting x = 3
From (4, 470), putting x = 4
From (5, 403), putting x = 5
Analyzing Option C:
Considering the equation
From (3, 470), putting x = 3
So, the approximately result is (3, 527)
From (4, 470), putting x = 4
So, the approximately result is (4, 378)
From (5, 403), putting x = 5
So, the approximately result is (5, 295)
Analyzing Option D:
Considering the equation
From (3, 470), putting x = 3
From (4, 470), putting x = 4
From (5, 403), putting x = 5
Therefore, from the above calculations and analysis, we conclude that Option C is the correct option.
In other words, the quadratic regression best fits the data set, as it gets very much close to the data values given in the data table.
The graph of the equation is also attached.
