For a certain drug, based on standards set by the United States Pharmacopeia (USP) - an official public standards-setting authority for all prescription and over-the-counter medicines and other health care products manufactured or sold in the United States, a standard deviation of capsule weights of less than 2 mg is acceptable. A sample of 12 capsules was taken and the weights are provided below: 98.8 100.3 98.4 101.5 | 100.7 98.8 101 98.6 100.2 99.6 100 100.3 The mean of the data set is 99.9; the sample standard deviation is 1.01; if the normality plot is not provided you may assume that the capsule weights are normally distributed. Construct a 95% confidence interval for the variance (standard deviation) of all capsule weight. i. Procedure: Select an answer ii. Assumptions: (select everything that applies) O Normal population O Simple random sample O Population standard deviation is known O Sample size is greater than 30 O Population standard deviation is unknown O The number of positive and neoative responses are both greater than 10
