A data set lists earthquake depths. The summary statistics are n = 500, x = 6.85 km, s = 4.68 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 μ. 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.
