Question
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 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?
Ο Β. Η: μ= 4.00 km
H: µ# 4.00 km
Ο Α. Ηo μ= 4.00 km
H1: µ<4.00 km
O C. H : μ= 4.00 km
H1: µ> 4.00 km
O D. Hp: µ#4.00 km
H1:µ = 4.00 km
Determine the test statistic.
(Round to two decimal places as needed.)
Identify the range of values for P-value. (You will not enter it here; you will use it to make your decsion below.)
State the final conclusion that addresses the original claim.
Ho. There is
evidence to conclude that the original claim that the mean of the population of earthquake depths is 4.00 km
correct.
