Problem 32 BSC

Large Data Sets. In Exercises, use the data from Appendix B to construct a scatterplot, find the value of the linear correlation coefficient r, and find either the P-value or the critical values of r from Table A-5 using α = 0.05. Determine whether there is sufficient evidence to support the claim of a linear correlation between the two variables. (Save your work because the same data sets will be used in Section 10-3 exercises.)

Earthquakes Refer to Data Set 16 in Appendix B and use the magnitudes and depths from the earthquakes.

Problem 32 BSC

Answer:

Step1 of 4:

We have Refer to Data Set 16 in Appendix B and use the magnitudes and depths from the earthquakes.

Step2 of 4:

We need to construct a scatterplot, find the value of the linear correlation coefficient r, and find either the P-value or the critical values of r from Table A-5 using α = 0.05. Determine whether there is sufficient evidence to support the claim of a linear correlation between the two variables.

A scatter plot is obtained by using Excel and the steps are as follows:

Enter the given data in Excel sheet

select data what we entered in Excel sheet go to insert choose scatterplot

then press ok.

Step3 of 4:

Consider,

...Mag(x) | Depth(y) | xy |
