Question 5 1 0/1 pt Details 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 8 capsules was taken and the weights are provided below 101.4 100.2 98.3 100.1 99.7 99.2 99.9 100.8 The mean of the data set is 100; the sample standard deviation is 0.95; if the normality plot is not provided you may assume that the capsule weights are normally distributed. Construct a 99% confidence interval for the variance of all capsule weight. i. Procedure: Select an answer ii. Assumptions: (select everything that applies) Sample size is greater than 30 The number of positive and negative responses are both greater than 10 Population standard deviation is known Population standard deviation is unknown Simple random sample Normal population ifi. Unknown parameter: Select an answer iv. Point estimate: Select an answer (Round the answer to 3 decimal places) Confidence level % and a also and 1 o Critical values: ( Round the answer to 3 decimal places) left - right- vi. Lower bound: ( Round the answer to 3 decimal places vii. Upper bound: (Round the answer to 3 decimal places) viii. Interpretation: We are confident that the true population variance is between and
