A data set lists earthquake depths. The summary statistics are n = 500, x=4.77 km, s=4.69 km. Use a 0.01 significance level to test the claim of a seismologist that these earthquakesare 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 statethe final conclusion that addresses the original claim.
