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”.
