Answer:
[tex]y=0.2x^2+1.1x+5[/tex]
Step-by-step explanation:
Quadratic regression is a statistical method that models the relationship between a dependent variable (y) and an independent variable (x) using a quadratic equation, allowing for the identification of a curved pattern in the data.
To find a model for the given data, input the data into a quadratic regression tool or statistical calculator.
After entering the data into a statistical calculator we get:
[tex]a = 0.2[/tex]
[tex]b = 1.1[/tex]
[tex]c = 5[/tex]
Substitute the found values of a, b and c into the quadratic regression formula, y = ax² + bx + c.
Therefore, the quadratic regression equation is:
[tex]\Large\boxed{\boxed{y=0.2x^2+1.1x+5}}[/tex]
