Given

x=12,4,4,12,7,4,3,7,7,7

y=20,15,15,19,18,17,15,18,16,19

An equation of the least squares regression line; plotting the points on a scatter plot, we can find the line of best fit

This scatter plot is shown below:

The parameters of the best fit

m= 0.495114 and C= 13.8827

The general equation of a line is y = mx + c

Therefore, the equation of the least-squares regression line

is


y=0.495x+13.883

x=12,4,4,12,7,4,3,7,7,7y=20,15,15,19,18,17,15,18,16,19find an equation of the least-example-1
