Use the Tornadoes data and your statistical expertise to answer the questions: Is it reasonable to claim that on average October has less tornado-related deaths than April (per year)?

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 of 3.68411 is below 4 we are confident that the number of tornado-related deaths is below 4.
  • b. Since P-value is not small we cannot claim that the number of tornado-related deaths is below 4.
  • c. Since confidence interval is above 4 we cannot claim that the number of tornado-related deaths is below 4.
  • 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.
