Use the magnitudes of the earthquakes listed in Data Set 21 “Earthquakes” and test the claim that the sample is from a population with a mean greater than 2.50. Use a 0.01 significance level.

Use the data set from Appendix B to test the given claim. Use the P-value method unless your instructor specifies otherwise.

Data Set 21: Earthquakes

Data are from 600 matched pairs (first five rows shown here) of magnitude>depth measurements randomly selected from 10,594 earthquakes recorded in one year from a location in southern California. Only earthquakes with a magnitude of at least 1.00 are used. MAGNITUDE is magnitude measured on the Richter scale and DEPTH is depth in km. The magnitude and depth both describe the source of the earthquake. The data are from the Southern California Earthquake Data Center.
