\begin_layout Subsection*
a.
 Percentage of variance explained by the regression
\end_layout

\begin_layout Standard
In table 15.11 we are given that the coefficient of multiple correlation
 equals 0.95.
 Our text explains that the coefficient of multiple correlation is the square
 root of the coeffiicient of determination.
 Therefore the coefficient of determination =
\begin_inset Formula $0.95^{2}=0.9025$
\end_inset

.
 The percent of variance explained by the regression is 100 times the coefficien
t of variation.
 In this case the percentage of variation explained by the regression is
 90.25%.
