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 2.5 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.

Assuming all conditions for conducting a hypothesis test are met, what are the null and alternative hypotheses?
O A. Ho: =2.5 miles
H:u<25 miles
O B. Ho: = 2.5 miles
H:u#2.5 miles
OC. Ho u<2.5 miles
H p=2.5 miles
O D. Ho: =2.5 miles
H:>2.5 miles
Identify the test statistic.
(Round to two decimal places as needed.)
