Use Tornadoes data and your statistical expertise to answer the questions: Is it reasonable to claim that on average October has less than four tornado-related deaths (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. 3.684118249
• d. 1.10683165
• e. None of these

11. Statistical Interpretation

• a. Since the confidence interval of 3.68411 is below 4, we are confident that the number of tornado-related deaths is below 4.
• b. Since the 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 assertion is reasonable.
• b. No, we cannot claim that the above assertion is reasonable.
