regression line and a correlation coefficient: ? 0.7 0.8 1.7 1.7
1.3 2.6 8.0 ? 1 2 2 1 0 1 5 The student claims that the regression
line does an excellent job of explaining the relationship between
the explanatory variable ? and the response variable ? . Is the
student correct?
a. Yes, because ?2=0.74 means that 74% of the variation in ? is
explained by the...
