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 2.8 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.   Hypothesis test​ results:           μ ​: Mean of variable             H0 ​ : μ=2.8             HA ​ : μ>2.8             Variable Sample Mean Std.
