Variables n = 307          = = 0.329 a = 0.05         po = 0.41 flavour 1: Null and Alternative Hypothesis The null guessing is the tested sample affinity being equal or slight than 41%. The alternative hypothesis is our sample proportion being greater than 41%. A one-tail test mustiness(prenominal) be utilise in order to conclude whether or not more than 40% of prescriptions are filled with generic medication. Ho : p ? 0.41 Ha : p > 0.41 rate 2: analyze Statistic The population proportion test statistic must be pulmonary tuberculosisd due to the statistic that has been selected to test, because it is a percentage. We therefore use the following equating to compute the Z-value: =         The following is a bell shape curve that describes the entropy that has just been calculated: a = 0.05                                     0.4981    Â!  Â Â Â Â           0...
