Question

What is the quadratic regression equation that fits these data

Answer 1

Rounded to two decimals the regression curve is:

Explanation:

Answer 2

Rounded to two decimals the regression curve is:

`y=-0.70\,x^2+2.37\,x+11.96`

Explanation:

The objective of this problem is to have you use a calculator and enter the data in to separate lists: one containing the x-values, and the other the correspondent y-values (following the same order).

Once the data is entered, you need to access the regression tool and request a quadratic form of regression.

You should get and image and resulting function as shown in the attached image.
