Question

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.
