19. 1 point Acecno-0---Och 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). Following are the results from a simple regression performed to relate waiting time to race: P = 51.5 + 19.3x + 2.6x2 where xp=1if the respondent identifies as black (and if not), and x2=1 if the participant identifies as other (O if not). The standard error of the slope for xyis 1.2, and for X2 is 2.5. The Ris 0.01 Suppose the x's were recoded as x1 = 1 for White (and o if not), and X2 =1 for Black (and o if not), and the following regression model was fit to the data with the recoded x values: $ = D.+BX+ B2. Will the p-value for testing the null that the slope for x =0(Ho:B-0) be statistically significant (-0.05)? a. Yes b. No The pennathadtarmiend 10h the information in
