Question
Can you help me find the test statistics & p-value
A data set lists earthquake depths. The summary statistics are n = 400, x= 4.96 km, s = 4.76 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? O A. Ho µ= 4.00 km H µ> 4.00 km O B. Ho p=4.00 km Hp<4 00 km O C. Ho µ#4.00 km D. Ho µ=4 00 km H, p= 4.00 km H. p#4.00 km Determine the test statistic. (Round to two decimal places as needed.)
