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 reasonable to say that cars with 8 cylinders have highway gas mileage (MPG) lower than the cars with 6 cylinders? 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.
