Apharmaceutical manufacturer forms tablets by compressing a granular material that contains the active ingredient and various fillers. the force in kilograms (kg) applied to the tablets varies a bit, with the n(12.2, 0.2) distribution. the process specifications call for applying a force between 11.5 and 12.5 kg. (a) what percent of tablets are subject to a force that meets the specifications? % (b) the manufacturer adjusts the process so that the mean force is at the center of the specifications, μ = 12 kg. the standard deviation remains 0.2 kg. what percent now meet the specifications? %
