The answer to the question is B. The test statistic is not between the critical values, so we reject the null hypothesis. There is sufficient evidence to support a claim of correlation between percentage of vote and income level.
<h3>What is the scatter plot?</h3>
This is the plot that shows the relationship between two different variables along a straight line. All of the points that are known to have a relationship between these variables would fall under this line. Other parts that fall outside the line are regarded as the outliers in the plot.
In this particular question, the outlier is seen to be outside of the critical values so we have to conclude that the solution is B. We fail to reject the null hypothesis.
There is a really easy way to do this problem and that is to use a graphing website
after punching in the functions:
A. depending of whether it is -5/(2x) or (-5/2)x: intersecting but not perpendicular or parallel B. These two lines are perpendicular C. Parallel lines D. intersecting but not perpendicular
