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 0.05 significance level. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, and conclusion for the test. Assume this is a simple random sample. Click the icon to view the sample data What are the hypotheses? O B. Ho u + 1.00 in magnitude H:u= 1.00 in magnitude O A. Ho: p= 1.00 in magnitude Hyu+1.00 in magnitude C. Ho: p= 1.00 in magnitude H4:p> 1.00 in magnitude OD. Ho u = 1.00 in magnitude Hu<1.00 in magnitude Identify the test statistic. Magnitudes of 50 earthquakes x - t= - (Round to two decimal places as needed.) Identify the P-value. The P-value is (Round to three decimal places as needed.) Choose the correct answer below. 0.710 0.740 1.640 1.330 1.620 1.830 0.920 1.000 1.490 0.840 Magnitude of Earthquake e 0.640 0.390 0.700 2.200 1.980 2.950 0.900 1.760 1.010 1.260 0.990 1.560 0.380 1.280 0.830 0.790 0.790 1.440 1.000 2.240 1.420 1.000 1.250 1.420 1.350 0.640 0.000 1.330 2.500 0.930 1.220 0.650 0.540 1.790 0.400 0.200 1.460 1.250 1.250 1.390 O A. Fail to reject Ho. There is sufficient evidence to conclude that the population of earthquakes has a mean magnitude greater than 1.00. OB. Reject Ho.

Answer 1

Ho: 4 = 1.00 H:>1.00 t = X-M Stro ; t = 1.184, S =0.588 naso t = 1.184 -1 2.12 0.588/150 P-value = T.DIST. RT (2.12,49) + Excel Juz -10.020 B Reject to நம
