using the tornado lengths (miles) to test the claim that the mean tornado length is greater than 2.3 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. a. Identify the test statistic. (Round to two decimal places as needed.) b. Identify the P-value. (Round to three decimal places as needed.)
