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 2.4 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. Variable Sample Mean Std. Err. DF T-Stat P-value Length 2.56317 0.213438 399 0.764484 0.2225 Assuming all conditions for conducting a hypothesis test are met, what are the null and alternative hypotheses? => 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. (fail to reject/reject) H0. There is (sufficient/not sufficient) evidence to support the claim that the mean tornado length is greater than 2.4 miles.

Assuming all conditions for conducting a hypothesis test are met, what are the null and alternative hypotheses?
=>
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.
(fail to reject/reject) H0. There is (sufficient/not sufficient) evidence to support the claim that the mean tornado length is greater than 2.4 miles.
