X = 2/3 + 5/6 + 4/6 + 5/6 = 9/6 = 3/2
The way you do this is 5322÷5 which equals 1064.4
The regression equation of the data values is y = 0.3x^2 - 2.8x +4.2
<h3>How to determine the regression equation?</h3>
Using a technology such as a graphing calculator, we simply input the data values in the graphing calculator and then wait for the result.
The x coordinates must be entered into the x values and the y coordinates must be entered into the y values
Using a graphing technology, the regression equation of the data values is y = 0.3x^2 - 2.8x +4.2
