K A data set includes data from 400 random tornadoes. The display from technology available below results from using the tomado lengths (miles) to test the claim that the mean tornado length is greater than 2.8 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. iClick the icon to view the display from technology.
