A data set lists earthquake depths. The summary statistics are n = 400, x = 6.43 km, s = 4.57 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 6.00, 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? O A. Ho: 1 = 6.00 km OB. Ho: H # 6.00 km Hy : H > 6.00 km Hy : p = 6.00 km O C. Ho H= 6.00 km O D. Ho: H = 6.00 km Hy: H
