Open Brains data. Test if the weight of people with Brain Volume = 1100 or more and the weight of people with Brain Volume less than 1100 are significantly different on average. Answer questions 13 to 16.

13. What test did you perform? (6.25 points)

  • a. Simple Regression
  • b. Multiple Regression
  • c. Two sided t-test
  • d. None of these

14. What is the P-value? (6.25 points)

  • a. 0.932448
  • b. 0.000826
  • c. 0.379046
  • d. None of these

15. What is the Statistical interpretation? (6.25 points)

  • a. The P-value is too large to have a conclusive answer.
  • b. The P-value is greater than 5% thus we are very certain that the averages are significantly different.
  • c. The P-value is greater than 5% we are not confident that the slope is not zero.
  • d. The P-value is smaller than 5% thus we are very certain that the averages are significantly different.
  • d. None of these

16. What is the conclusion? (6.25 points)

  • a. Since the test is inconclusive the conclusion is inconclusive as well.
  • b. The test is inconclusive and more data is needed.
  • c. We can claim that the weight of people with Brain Volume = 1100 or more and the weight of people with Brain Volume less than 1100 are significantly different on average.
  • d. We cannot claim that the weight of people with Brain Volume = 1100 or more and the weight of people with Brain Volume less than 1100 are significantly different on average.
  • e. None of these
