Adata 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 2.6 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. click the icon to view the display from technology. what are the null and alternative? hypotheses?

a. upper h0? : mu ? < 2.6 miles upper h 1? : mu ? equals = 2.6 miles
b. upper h0? : mu ? equals = 2.6 miles upper h1? : mu ? not equals ? 2.6 miles
c. upper h0? : mu ? equals =2.6 miles upper h1? : mu ? less than < 2.6 miles
d. upper h0? : mu ? equals = 2.6 2.6 miles upper h 1 h1? : mu ? > 2.6 miles
identify the test statistic. nothing ? (round to two decimal places as? needed.)
identify the? p-value. nothing ? (round to three decimal places as? needed.) state the final conclusion that addresses the original claim.
? (fail to reject, reject) upper h0. there is ? ( sufficient, not sufficient) evidence to support the claim that the mean tornado length is greater than 2.6 miles
