A 8.3.12 Question Help A data set includes data from 500 random tornadoes. The display from technology available below results from using the tornado lengths (miles) to test the claim that the mean tornado length is greater than 2.5 miles. 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. A Click the icon to view the display from technology. Assuming all conditions for conducting a hypothesis test are met, what are the null and alternative hypotheses? O A. Ho: µ=2.5 miles H4: µ#2.5 miles OB. Ho: H= 2.5 miles H: µ> 2.5 miles O C. Ho: H<2.5 miles O D. Ho: H= 2.5 miles H1: µ= 2.5 miles H1: µ<2.5 miles Identify the test statistic. (Round to two decimal places as needed.)
