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 21 capsules was taken and the weights are provided below: 98.1 100.2 98.1 98 98.7 99.9 101 99 99.4 98.7 100.8 99.3 98.4 99.9 101.5 100.7 99.1 99.8 99.5 99.3 101.9 The mean of the data set is 99.59; the sample standard deviation is 1.119; 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 weights. i. Procedure: Select an answer ii. Assumptions: (select everything that applies) O Normal population The number of positive and negative responses are both greater than 10 O Sample size is greater than 30 O Simple random sample Population standard deviation is known O Population standard deviation is unknown iii. Unknown parameter: Select an answer
