[Video] Q16: The scatterplot above shows the average production cost, in cents per pound, of coffee in ecuador for the years from 2002 to 2012. aline of best fit is also drawn. which of the following is closest to the difference, in cents per pound, between the actual average production cost in 2012 and the average production cost in 2012 predicted by the given line of best fit?

Explanation for Question 16 From the Math (Calc) Section on the 2018 May Sat

Question 16 asks, which of the following is closest to the difference in cents 2 per pound, between the actual average production in 2012 and the average 3 production in 2012 predicted by the given line of best fit. 4 So let's go back up to the graph and go to 2012 and see. 5 So 2012 is here on the graph. 6 The line of best fit predicts that the average production cost is 7 going to be about 82 cents per pound. 8 And the actual cost of production is at 90. 9 So all we have to do is subtract 82 from 90, 10 which gives us eight. And so we know that the answer is.
