Test: Fall 2021 Final Exam [fixed] Question 3 of 20 This test: 86 point(s) possible This question: 7 point(s) possible Resume later A simple linear regression was performed with the following results: TempA = - 3.437 + 0.01077 CarbonDioxide S 0.088383 R-sq 87.66% R-sq(adj) 86.91% 1 What is the best interpretation of the y-intercept? O A. We predict that a year with a Carbon Dioxide level of 0 ppm will have a temperature anomaly (TempA) of - 3.437 degrees Celsius. O B. We predict that a year with a Carbon Dioxide level of - 3.437 ppm will have a temperature anomaly (TempA) of 0.01077 degrees Celsius. O C. We predict that a year with a Carbon Dioxide level of - 3.437 ppm will have a temperature anomaly (TempA) of 0 degrees Celsius. D. We cannot interpret the value of the y-intercept because X = 0 is an extrapolation for this dataset. O. E. We predict that a year with a Carbon Dioxide level of 0.01077 ppm will have a temperature anomaly (TempA) of - 3.437 degrees Celsius. 2. What is the best interpretation of the slope? O A. For every - 3.437 ppm increase in Carbon Dioxide level, we expect that the average temperature anomaly will increase by 0.01077 degrees Celsius. O B. For every 0.01077 ppm increase in Carbon Dioxide level, we expect that the average temperature anomaly will increase by 1 degree Celsius. O C. For every 0.01077 ppm increase in Carbon Dioxide level, we expect that the average temperature anomaly will decrease by 3.437 degrees Celsius. O D. For every 1 ppm increase in Carbon Dioxide level, we expect that the average temperature anomaly will increase by 0.01077 degrees Celsius. 3. What is the value of the correlation between TempA and CarbonDioxide? - 3.426 (Round your answer to 3 decimal places.) 4. How do we know that the sign of the correlation is positive? A. The sign of the slope is positive O B. The sign of the y-intercept is positive c. The sian of the R-squared value is positive VI ([,1) More Time Remainin MacBook Pro esc % A @ # $ 5 6 4 2
