Question

Construct the scatter plot for the following data. From the plot does there appear to be a linear correlation?

Data

x	2	-4	-2	-1	-2	-1	-4	6	-5	-2
y	-1	-7	2	-7	4	-2	-5	4	-4	-5

2. Find the value of the linear correlation coefficient.

3. Perform a hypothesis test on the claim that there is a linear correlation. Does there appear to be a linear correlation? Why or why not?

(Use the traditional method)

List

the null and alternative hypothesis,
the critical value,
the test statistic,
Draw the graph and label the test statistic, critical value and rejection regions.

Reject or fail to reject?

State the conclusion

Definition Definition Representation of the direction and degree of correlation in graphical form. The grouping of points that are plotted makes it a scatter diagram. A line can be drawn showing the relationship based on the direction of points and their distance from each other.
