    \item Which statement characterises the data shown on the scatter diagram?

\begin{minipage}{8cm}
\begin{enumerate}[1.]
    \item Weak, positive, linear trend
    \item Moderate, positive, linear trend
    \item Moderate, negative, linear trend
    \item Strong, negative, linear trend
\end{enumerate}

    \item For the scatter diagram shown, what is the value of $r$?

\begin{minipage}{8cm}
\begin{enumerate}[1.]
    \item $-1 < r < -0.7$
    \item $-0.5 < r < -0.3$
    \item $0.3 < r < 0.5$
    \item $0.7 < r < 1$

    \item For the scatter diagram shown, what is the value of $r$?

\begin{minipage}{8cm}
\begin{enumerate}[1.]
    \item $-1 < r < -0.7$
    \item $-0.5 < r < -0.3$

    \item For the scatter diagram shown, the Pearson's coefficient $r$ was found to be $-0.6$.
The point $(4, 9)$ was found to be recorded incorrectly and should have been plotted as $(4, 1)$.
Based on this change, what is the correct coefficient $r$?

\begin{minipage}{8cm}
\begin{enumerate}[1.]
    \item Positive but closer to $0$
    \item Positive but closer to $1$
    \item Negative but closer to $0$
    \item Negative but closer to $-1$
\end{enumerate}

    \item A scatter diagram is shown with its line of best fit.
What is the equation of the line of best fit?

\begin{minipage}{8cm}
\begin{enumerate}[1.]
    \item $y = 4x - 3$
    \item $y = \dfrac{4}{3}x + 1$
    \item $y = \dfrac{4}{3}x - 1$
    \item $y = \dfrac{3}{4}x + 1$
\end{enumerate}
