Test if there is a significant difference in the death by Hurricanes and Min Pressure measured. Answer the questions for Assessment. (Pick the closest answer)

7. What is the P-value?

  • a. #DIV/0!
  • b. 0.384808843
  • c. 0.634755682
  • d. None of these

8. What is the Statistical interpretation?

  • a. The P-value is too large to have a conclusive answer.
  • b. The P-value is too small to have a conclusive answer.
  • c. ​​The P-value is much smaller than 5% thus we are certain that the average of hurricane deaths is significantly different from average min pressure.
  • d. None of the above.

9. What is the conclusion?

  • a. The statistics does not agree with the intuition since one would expect that stronger hurricanes to be deadlier.
  • b. ​​Statistical interpretation agrees with the intuition, the lower the pressure the stronger the hurricanes.
  • c. Statistics confirms that hurricanes’ pressure does relate to the death count.
  • d. The test does not make statistical sense, it compares “apples and oranges”.
