A data set lists earthquake depths. The summary statistics are n=600, x= 4.35 km, s=4.71 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 altemative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim. What are the null and alternative hypotheses? O A. H: u#4.00 km O B. Ho: u=4.00 km H:u=4.00 km H;:u#4.00 km OC. Ho: =4.00 km H;:p<4.00 km OD. Ha: u4.00 km H: p>4.00 km

Confidence Intervals

When we calculate intervals in probability and statistics, it can be simply termed as finding out a confidence interval. The confidence interval is usually calculated from the data set which is observed. The value of the parameter that needs to be calculated is present here only.
