DATA IN COMMENT BELOW
In what follows use any of the following tests/procedures: Regression, multiple regression, confidence intervals, one sided T-test or two sided T-test. All the procedures should be done with 5% P-value or 95% confidence interval.Some answers are approximated, choose the most appropriate answer. Open Cars04 data. SETUP: Is it true that average (retail) cost for the cars with 6 cylinders is higher than $35000? Given the data your job is to help answer this question.
I. What test/procedure did you perform? (6.66 points)
- a. One sided T-test
- b. Two sided T-test
- c. Regression
- d. Confidence interval
II. Statistical interpretation? (6.66 points)
- a. Since P-value is small we are confident that the slope is not zero.
- b. Since P-value is small we are confident that the averages are different.
- c. Since P-value is too large the test is inconclusive.
- d. None of these.
III. Conclusion? (6.66 points)
- a. Yes, we can confirm that this was a reasonable claim.
- b. No, we cannot confirm that this was a reasonable claim.
Homework Answers
I) answer: a) One sided T-test
II) Answer: d) None of these.
III) Answer b) No, we cannot confirm that this was a reasonable claim.
