Description: A data set lists earthquake depths. The summary statistics are n= 400, x= 4.85 km, s = 4.52 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 to4.00. Assume that a si

The sample statistics are : sample size =n=400sample mean =x=4.85 kmsample s.d=s=4.52 km To test for the significant difference in the population mean value, z-test is used. The null and alternative hypothesis are : Ho : μ=4.00 kmH1 : μ≠4.00 km Answer : B The test statistics is given by : t=x-μs/n~tn-1 [Note : When the population standard deviation is unknown, then it's estimate from sample is used and t-test is applied, but because the sample size is extremely large, t-distribution is assumed to approximately follow normal distribution.] z=4.85-4.004.52/400=3.761 The p-value for the z-score at α=0.01 is 0.0001 Decision Rule : reject the null hypothesis when p-value is less than alpha level of significance, accept otherwise. Reject Ho. There is sufficient evidence to conclude that the original claim that the mean of the population of earthquake depths is 4.00km incorrect.
