In what follows use any of the following tests/procedures:Regression, multiple regression, confidence intervals, one sidedT-test or two sided T-test. All the procedures should be done with5% P-value or 95% confidence interval.Some answers areapproximated, choose the most appropriate answer.OpenBrains data. SETUP: Scientists speculate that the heavier body thelarger the human brain (Volume). Given the data your job is toconfirm or disprove this assertion.
I. What test/procedure did you perform? (6.66points)
- a. One sided T-test
- b. Two sided T-test
- c. Regression
- d. Confidence interval
II. Statistical interpretation? (6.66points)
- a. Since P-value is small we are confident that the slope isnot zero.
- b. Since P-value is small we are confident that the averagesare different.
- c. Since P-value is too large the test is inconclusive.
- d. None of these.
III. Conclusion? (6.66 points)
