A data set includes data from 400 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 2.3 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. 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: u < 2.3 miles He: = 2.3 miles OC. Ho: u = 2.3 miles H:u> 2.3 miles OB. Ho: u = 2.3 miles H: 4 < 2.3 miles OD. Ho: u = 2.3 miles H4:2.3 miles
Х Display from technology Hypothesis test results: u: Mean of variable Ho : p = 2.3 HA:u > 2.3 Variable Sample Mean Std. Err. DF T-Stat Length 2.88311 0.293049 399 1.989804 P-value 0.0236
