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 1.8 mg is acceptable. A sample of 46 capsules was taken and the weights are provided below: 119.5 117.2 120.8 120.4 120.5 118.6 121.2 123.7 118.5 117.1 119 118.7 121.4 120.5 121.8 119.2 121 116.5 121.8 119.7 119.9 119.5 121.5 123.8 121.7 122.7 115.5 119.7 122.3 122.3 116.6 118.6 120.4 122.5 122.4 123.5 120.1 121.1 119.9 120.1 119.3 116.5 118.7 118.1 119.6 123.6 (Note: The average and the standard deviation of the data are respectively 120.2 mg and 2.1 mg.)

(Note: The average and the standard deviation of the data
are respectively 120.2 mg and 2.1 mg.)
At 1% significance level, test the claim that the standard
deviation of capsule weights of the drug is greater than 1.8
mg.
Procedure: Select an answer
Assumptions: (select everything that applies)
Simple random sample
The number of positive and negative responses are
both greater than 10
Population standard deviation is unknown
Population standard deviation is known
Sample size is greater than 30
Normal population
