Question

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 0.01 significance level. Identify the null? hypothesis, alternative? hypothesis, test? statistic, P-value, and conclusion for the test. Assume this is a simple random sample.

Choose the correct answer below. A.Reject H0. There is sufficient evidence to conclude that the population of earthquakes has a mean magnitude greater than 1.00. B. Reject H0. There is insufficient evidence to conclude that the population of earthquakes has a mean magnitude greater than 1.00. C. Fail to reject H0. There is sufficient evidence to conclude that the population of earthquakes has a mean magnitude greater than 1.00. D. Fail to reject H0. There is insufficient evidence to conclude that the population of earthquakes has a mean magnitude greater than 1.00.

          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 0.01 significance level. Identify the null? hypothesis,
alternative? hypothesis, test? statistic, P-value, and
conclusion for the test. Assume this is a simple random sample.
