The answer is a number from your printout. Write the number below, and also circle it on your printout. On the printout, write ``Question \ref{eqslopesF}" beside the number. % F = 0.30 \vspace{5mm} \item \label{eqslopesP} What is the $p$-value? The answer is a number from your printout. Write the number below, and also circle it on your printout. On the printout, write ``Question \ref{eqslopesP}" beside the number. % p = 0.7440 \vspace{5mm} \item In plain, non-statistical language, what do you conclude from this test? \emph{Do not say anything about regression lines or slopes. Express the conclusion in another way.} \vspace{10mm} \end{enumerate} \item (4 Points) \label{racediff} Base this on the model with no interactions. Controlling for mother's weight, are there average race differences in the baby's weight? \begin{enumerate} \item \label{racediffF} What is the value of the test statistic \emph{for the initial test}? The answer is a number from your printout. Write the number below, and also circle it on your printout. On the printout, write ``Question \ref{racediffF}" beside the number. % F = 5.19 \vspace{5mm} \item \label{racediffP} What is the $p$-value? The answer is a number from your printout. Write the number below, and also circle it on your printout. On the printout, write ``Question \ref{racediffP}" beside the number. % p = 0.0064 \vspace{5mm} \item In plain, non-statistical language, what do you conclude? \emph{Base your conclusions on the multiple comparisons, using joint $\alpha = 0.05$.} \vspace{10mm} \end{enumerate} \item (2 Points) \label{Bcritical} When you treated the Studentized deleted residuals as test statistics with a Bonferroni correction, what critical value did you use? The answer is a number from your printout. Write the number below, and also circle it on your printout. On the printout, write ``Question \ref{Bcritical}" beside the number. % 3.7199023 \end{enumerate} \vspace{10mm} \begin{center}\textbf{Please attach your log file and your list file.} Make sure your name is written on both files. \end{center} \end{document}
