A data set lists earthquake depths. The summary statistics are n = 400, x = 6.45 km, s = 4.65 km. Use a 0.01 K 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: H # 6.00 km O B. Ho: H= 6.00 km H1: H= 6.00 km H1: H > 6.00 km &C. Ho: H = 6.00 km O D. Ho: H = 6.00 km H1: u # 6.00 km H1: H
