Question:
Refer to Data Set 21"Earthquakes" in Appendix B and use the depths and magnitudes from the earthquakes. Does it appear that depths of earthquakes are associated with their magnitudes?
MAGNITUDE ________ DEPTH
2.45 ................... 0.7
3.62 ................... 6.0
3.06 ................... 7.0
3.30 ................... 5.4
1.09 ................... 0.5
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-6 using a significance level of α = 0.05. Determine whether there is sufficient evidence to support the claim of a linear correlation between the two variables.
