I was able to get the confidence interval but what am I missing to get the estimate mean difference?Any time I plug in some numbers I'm not even close to any of these results in minutes

23. 1 point A simple linear regression is fit to estimate the relationship between waiting times and systolic blood pressure (SBP). The resulting regression equation is: " = 65.6+ -0.06x1 , where x1= SBP (mmHg). The standard error of the slope for x1 ( SE(B,) ) is 0.02. The R2 for the model is less than 0.01. - Using these regression results, estimate the mean difference (and 95% CI) in waiting times for patients admitted to the ED with a SBP measure of 200 mmHg, and patients admitted to the ED with a SBP measure of 175 mmHg. a. -0.06 minutes (-.10, -0.02) CI = Slope + 2 (SE) b. -1.5 minutes (-2.5, -0.5) - 0.06 + 2 ( 0. 02 ) - - 0.02 c. - 60 minutes (-100, -20) - 0. 06 - 2(0. 02) =-0.1 d. - 15 minutes (-25, -5) 1506 416 - 6 Pot ( 25 ) - 6:1 .4. 1 p simple linear regression is fit to estimate the relationship between waiting times and systolic ic
