A data set lists earthquake depths. The summary statistics are nequals600, x overbarequals6.69 km, sequals4.25 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.
Solutions
Expert Solution
Solution:
The provided sample mean is Xˉ=6.69 and the sample standard deviation is s = 4.25
sample size is n = 600
(5) Conclusion
It is concluded that the null hypothesis Ho is rejected. Therefore, there is enough evidence to claim that the population mean μ is different than 6, at the 0.01 significance level.

The following summary statistics were
based on earthquake depth measurements in kilometers (km) randomly
selected from 10, 594 earthquakes recorded in one year from a
location in Southern California. The summary statistics are n =
50,
x=9.81
km, and s = 5.01 km. Show work:
Use a 0.01 significance level to test the claim of a
seismologist that these earthquakes are from a population with mean
depth equal to 10 km.
Test the claim by constructing an appropriate confidence
interval.
