Upload CARS data. SETUP: It is believed that Jaguars' Highway mileage is above 20 mpg. Given the data your job is to confirm or disprove this belief. (CAREFULL: sort the data in order to extract the needed information).

5. What test/procedure did you perform?

• a. One-sided t-test
• b. Two-sided t-test
• c. Regression
• d. ??Confidence interval

6. What is the P-value/margin of error?

• a. 0.161902527
• b. 1.443714665
• c. 6.149555
• d. ??8.065421
• e. ??None of these

7. Statistical Interpretation

• a. Since P-value is very small we are confident that the average mpg is above 20.
• b. Since P-value is large we cannot claim that the averages are different.
• c. Since P-value is very small we are confident that the slope of regression line is not zero.
• d. ??None of these.

8. Conclusion

• a. Yes, I am confident that the above claim is correct.
• b. No, we cannot claim that the above claim is correct.
