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 2.4 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. Hypothesis test results: μ : Mean of variable H0 : μ=2.4 HA : μ>2.4 Variable Sample Mean: 2.54848 std err:0.261196 DF:499 t stat: 0.568462 p value: 0.2850 what is the t stastistic? (round to two decimal places as needed) what is the p value? (round to three decimal places as needed) State the final conclusion that addresses the original claim. _____ H0. There _____ sufficient evidence to support the claim that the mean tornado length is greater than 2.4 miles
