ocedures should be done with 5% P-value or 95% confidence interval. pload CARS data. SETUP: It is believed that BMW prices (Suggested price) are higher than 40000. Given the data your job is to confirm or disprove this elief . (CAREFULL: sort the data in order to extract the needed information) What test/procedure did you perform? O a. One-sided t-test Ob. Two-sided t-test O c. Regression O d. Confidence interval 2. What is the P-value/margin of error? Oa 0.161902527 Ob. 14222.08354 O c. 8594.31906 Od. 8.065421 Oe. None of these 3. Statistical interpretation O a. Since P-value is very small we are confident that the average Price is above 40000. O b. Since P-value is very small we are very confident that the averages are different. O c. Since P-value is very small we are confident that the slope of regression line is not zero. Od. None of these. 4. Conclusion
