The following summary statistics were based on earthquake depth measurements in kilometers (km) randomly selected from 10, 594 earthquakes recorded in one year from a location in Southern California. The summary statistics are n = 50, x=9.81 km, and s = 5.01 km. Show work:

Use a 0.01 significance level to test the claim of a seismologist that these earthquakes are from a population with mean depth equal to 10 km.
Test the claim by constructing an appropriate confidence interval.
What are the null and alternative hypotheses?
What is the value of α= significance level?
Is the test two-tailed, left-tailed or right-tailed?
What is the test statistic and what is its distribution?
What is the value of the test statistic?
What is the P-value?
What is (are) the critical value(s)?
How would you state a conclusion that addresses the original claim?

A data set lists earthquake depths. The summary statistics are nequals500, x overbarequals4.76 km, sequals4.33 km. Use a 0.01 significance level to test the claim of a seismologist that these earthquakes are from a population with a mean equal to 4.00. Assume that a simple random sample has been selected. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim. What are the null and alternative hypotheses?
