Question
8.3-4
A data set lists earthquake depths. The summary statistics are n= 500, x= 4.36 km, s= 4.24 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
daim
What are the null and alternative hypotheses?
O A. Ho p= 4.00 km
H, p> 4.00 km
O B. Ho = 4.00 km
H u<400 km
OC. Ho 4.00 km
H, p=4.00 km
D. Ho 4.00 km
H, u4.00 km
nts
Determine the test statistic.
O(Round to two decimal places as needed)
