data set lists earthquake depths. The summary statistics are
n=400,
x=6.47
km,
s=4.86
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.
