True or false: In regression modeling, it is more important to correctly specify the independent variables than to maximize the value of R-squared. True False
True or False. In simple linear regression, about $95 \%$ of the $y$ -values in the sample will fall within $2 s$ of their respective predicted values.
Are the statements true or false? Give reasons for your answer. If $g(r, s)=r^{2}+s,$ then for fixed $s,$ the partial derivative $g_{r}$ increases as $r$ increases.
