<PRE><B>Question 615922</B>
- If the correlation coefficient is -0.53, what is the sign of the slope of the regression line?


&lt;font color=&quot;red&quot;&gt;Answer: Since the correlation coefficient is &lt;u&gt;&lt;b&gt;negative&lt;/b&gt;&lt;/u&gt;, the slope of the regression line is &lt;u&gt;&lt;b&gt;negative&lt;/b&gt;&lt;/u&gt;&lt;/font&gt;

- As the correlation coefficient increases from 0.51 to 0.56, do the points of the scatter plot move toward the regression line, or away from it?


&lt;font color=&quot;red&quot;&gt;Answer: as the correlation coefficient increases to 1, the points will move &lt;u&gt;&lt;b&gt;closer&lt;/b&gt;&lt;/u&gt; to the regression line. Remember that a larger correlation coefficient (in absolute value) means a stronger correlation.&lt;/font&gt;
