Question 1
A scatterplot of log(Y) vs. log(X) reveals a linear pattern with very little scatter. It is probably true that…
◦ the correlation between
X and
Y is near 0.
◦ the scatterplot of
Y vs
X shows a linear association.
◦ the calculator's LnReg function will model the association between
X and
Y.
◦ the residuals plot for regression of
Y on
X shows a curved pattern.
◦ the correlation between
X and
Y is near +1.
