7. A simple linear regression was performed to relate average ED waiting times to subject's sex, with X1 coded as 1 for male and O for female. The regression results are as follows: Û =57.4+-2.5X7, and the estimated standard error of the slope fe sex is 0.95. The R2 for this regression is <.01. Suppose xq had instead been coded as 1 for females, and o for males. What would the slope value for xq be in the regression of waiting time on xq with this new coding schema for females, O for males?) a. 57.4 minutes b. 54.9 minutes c. 2.5 minutes d. -2.5 minutes
