please answer: iv, v, vi
iv:
sample variance
sample mean
sample proportion
![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 15 capsules was taken and the weights are provided below:
100.5
99.6
100.7
100
99.8
100.3
101
100.4
98.7
99.9
98.8
99.2
99.7
98.6
99.2
The mean of the data set is 99.8; the sample standard deviation is 0.75; if the normality plot is not
provided you may assume that the capsule weights are normally distributed.
Construct a 90% confidence interval for the variance (standard deviation) of all capsule weight.
