9. Based on this graphic, and the results from the regression what can you say about the relationship between waiting times and sex? Also of interest is whether there are any differences in the waiting time distributions by self-reported race of the survey participants. Participants classified themselves into 1 of 3 racial categories: while, black, other (did not identify as either black or white). Below are the results from a simple regression performed to relate waiting time to race: where x = 1 if the respondent identifies as black (and if not), and x=1 if the participant identifies as other (O if not). The standard error of the slope for x, is 1.2, and for xxis 2.5. The Ris 0.01 Based on this regression model, what is the estimated mean waiting time for participants who identify racially as : 10. White 11. Black 12. Other Based on these regression results: 13. What is the estimated mean difference in waiting times (and 95% CI) for Black compared to White? 14. What is the estimated mean difference in waiting times and 95% CI) for Other compared to White? 15. What is the estimated mean difference in waiting times for Black compared to other? 16. What is the interpretation of the R value? Now suppose the x's were coded as x, - 1 for White (and if not), and x =1 for Black (and O if not), and the following regression model was fit to these data: 17. What would the value of be from this model? 18. What would the value of be from this model? 19. Would the p-value for testing be statistically significant (a 0.05)?
