A pharmaceutical manufacturer forms tablets by compressing a granular material that contains the active ingredient and various fillers. The force in kilograms (kg) applied to the tablet varies a bit and follows the Normal distribution with mean 5 kg and standard deviation 0.2 kg. The process specifications call for applying a force between 11.2 and 12.2 kg. What percent of tablets are subject to a force that meets the specifications? The manufacturer adjusts the process so that the mean force is at the center of the specifications, μ = 11.7 kg. The standard deviation remains 0.2 kg. What percent now meets the specifications
