Question

Use regression to solve the problem. Round numbers to the nearest hundredth. 7) The first column shows the independent variable (x). The second column shows the dependent variable (y). Find the quadratic regression equation.

A) y = -0.02x2 + 2.90 x + 3.70
C) y = -0.01x2 + 3.80 x +3.20
B) y = -0.01x2 + 3.20 x + 3.70
D) y = -0.02x2 + 3.20 x + 3.20​

Answer 1

Plot the points on the graphing calculator. Then generate a quadratic regression equation.

y = -0.01x² + 3.20x + 3.70

The correct answer is B.
