Linear regression is used commonly to predict analysis
it can also be used to identify the strength of the effect that the independent variable have on dependent variable
the equation for the linear regression is
y = 13.61x + 150.87
We have two variable x and y
x = fat in grams
to calculate the residual for 10 grams using the above equation
y = 13.61x + 150.87
where x = 10 grams
y = 13.61 (10) + 150.87
y = 136.1 + 150.387
y = 286.8
the answer is 268.8 option C
