15. The accompanying data table lists the magnitudes of 50
earthquakes measured on the Richter scale. Test the claim that the
population of earthquakes has a mean magnitude greater than 1.00.
Use a 0.05 significance level. Identify the null hypothesis,
alternative hypothesis, test statistic, P-value, and conclusion
for the test. Assume this is a simple random sample.

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.

Identify the null and alternative hypothesis(in symbolic and
sentence form), test statistic, P-value(or critical values),
conclusion about the null hypothesis, and final conclusion that
addresses the original claim (Don’t just say Reject the null
hypothesis or fail to reject the null hypothesis).

Identify the null hypothesis, alternative hypothesis, test
statistic, P-value, conclusion about the null hypothesis, and final
conclusion that addresses the original claim. The health of
employees is monitored by periodically weighing them in. A sample
of 54 employees has a mean weight of 183.9 lb. Assuming that ? is
known to be 121.2 lb, use a 0.10 significance level to test the
claim that the population mean of all such employees weights is
less than 200 lb.

N=500, x =4.39 km, S=4.31 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.
