Iam being asked to calculate and plot residuals and i don't know how my x values are 13.8, 18, 16,7, 18, 0.7, 21.9, 9.2, 19.5, 15.5, 0.7 and my y values are 1.42, 3.7, 3.21, 4, 1.11, 3.69, 2.23, 3.77, 3.92, 3.92, 1.11. and i will insert a picture of the scatterplot i made if that .

Which term best describes the association between variables a and b? no association a negative linear association a positive linear association a nonlinear association a scatterplot with an x axis labeled, variable a from zero to ten in increments of two and the y axis labeled, variable b from zero to one hundred forty in increments of twenty with fifteen points in a positive trend.

What’s the answer ? use the picture to see the problem
