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 2.6 miles. Use a 0.05 significance level. Use the display
to identify the ull and alternative hypotheses, test statistic, and P-value.
State the final conclusion that addresses the original claim.
Hypothesis test results:
p. Mean of variable
Ho p=2.6
HA H 2.6

Reject Ho. There is not sufficient evidence to support the claim that the mean tornado length is greater than 26 miles.
O B.
Reject Ho. There is sufficient evidence to support the claim that the mean tornado length is greater than 2.6 miles
Fail to reject Ho. There is sufficient evidence to support the claim that the mean tornado length is greater than 2.6 miles
C.
