Using a calculator, it is found that the equation of linear regression that fits the data is given by:

C. y=-0.295x+20.667

How to find the equation of linear regression using a calculator?

To find the equation, we need to insert the points (x,y) in the calculator.

In this problem, the points are given as follows: (1, 20.71), (2, 19.69), (3, 19.61), (4, 19.64), (5, 19.26). Hence the equation is:

Doing this, the equation is:

y = -0.295x + 20.667.

Hence option C is correct.
