DATA: https://www.limes.one/Content/DataFiles/Tornadoes.txt

9. What test/procedure did you perform?

a. One-sided t-test

b. Two-sided t-test

c. Regression

d. Confidence interval

10. What is the P-Value/margin of error?

a. 0.723595771

b. 1.8

c. 0.007110117

d. 0.003555059

e. None of these

11. Statistical Interpretation

a. Since confidence interval does not include 25 we are confident that the number of tornado-related deaths is below 25.

b. Since P-value is small we are confident that the number of tornado-related deaths is below 25.

c. Since confidence interval includes 25 we cannot claim that the number of tornado-related deaths is below 25.

d. None of these.

12. Conclusion

a. Yes, I am confident that the above claim is reasonable.

b. No, I cannot claim that the above claim is reasonable.
