I need help with this Statistic question



This Question: 1 pt 17 of 20 (6 complete) This Test: 20 pts possible Park officials make predictions of times to the next eruption of a particular geyser, and collect data for the errors (minutes) in those predictions. The display from technology available below results from using the prediction errors to test the claim that the mean prediction error is equal to zero. Comment on the accuracy of the predictions. Use a 0.05 significance level. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim. i Click the icon to view the display from technology. What are the null and alternative hypotheses? O A. Ho: H= 0 minutes O B. Ho: H = 0 minutes H, : p = 0 minutes H, : p = 0 minutes O C. Ho: H = 0 minutes O D. Ho: p= 0 minutes Hy : p#0 minutes H : p > 0 minutes Identify the test statistic. (Round to two decimal places as needed.) Identify the P-value. (Round to three decimal places as needed.) State the final conclusion that addresses the original claim. Ho. There is evidence to conclude that the original claim that the mean prediction error is equal to zero correct.
