question 44

Essay

Researchers studying the relationship between the number of fat grams and the net weight in ounces of a fun size package of peanut M & M's believe that the deterministic component of the relationship is a straight line. A scatterplot shows that even though the general trend is linear, the points do not fall exactly on a straight line. Describe two factors that might account for the random component of this regression model.
