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 Air_Traffic data. SETUP: It is believed that there is more air traffic (on average) in December than in January. Given the data your job is to confirm or disprove.
I. What test/procedure did you perform?
a. One sided T-test
b. Two sided T-test
c. Regression
d. Confidence interval
II. Statistical interpretation?
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?
a. Yes, this is a reasonable belief.
b. No, we cannot confirm that this is a reasonable belief.
