8. A simple linear regression was performed to relate average ED waiting times to subject's sex, with X7 coded as 1 for male and O for female. The regression results are as follows: ลท =57.4+-2.5X7, and the estimated standard error of the slope foi sex is 0.95. The R2 for this regression is <.01. - Suppose xy had instead been coded as 1 for females, and O fo males. What would the 95% CI for the slope of xy be for the regression of waiting time on Xy with this new coding schema (1 for females, O for males?) a. (55.5, 59.3) minutes b. (53.0, 56.8) minutes c. (0.6, 4.4) minutes d. (-4.4,-0.6) minutes
