With n_drug = 20, Mean drug = 100 mm Hg, Sdrug = 5. The values for the placebo were n plac = 20, mean = 106 and standard deviation = 5.1. With alpha = 0.05 find the lower confidence limit for the difference between means of the Placebo - Drug. Include at least 4 significant figures in your calculations, report your answer to the nearest tenth of a mm of Hg.
