A food distributor conducts regular surveys of consumer spending on its products. The average weekly household spending (in doll
ars) on regular pasta and gluten-free pasta for each of 12 states was recorded. A scatterplot of spending on regular pasta versus gluten-free pasta is shown. Which of the following statements is true?
Graph shown below
A. Point (7.2, 10) is an outlier.
B. There is clear evidence of a negative association between spending on gluten-free pasta and regular pasta.
C. The equation of the least-squares regression line for this plot is approximately ŷ = 3.8 + two thirds times x.
D. The correlation for these data is r = 1.
E. The observation in the upper right corner of the plot is influential for the least-squares regression line.
