The weight variation test is performed by taking few tablets from the batch and finding out their average weight, say 'x'.then individual tablets are weighed and deviation or % deviation from average weight is determined. There is certain acceptable range for the tablets falling in the certain weight ranges.
The United States Pharmacopeia (USP) specifies a weight variation limit of ±5% for tablets with a weight of 300 mg or less and ±3% for tablets weighing more than 300 mg. This means that individual tablets should not deviate more than these percentages from the average weight of the tablets in a batch.
As per the Indian Pharmacopoeia, the weight variation limit for tablets is generally specified as not more than 5% by weight deviating from the average weight of the tablets. This ensures uniformity in dosage delivery and quality control during manufacturing.

To analyze the variation of vitamin supplement tablets, calculate the mean and standard deviation of the weights of the 14 tablets. With a 90% confidence level, determine the margin of error using the t-distribution. This margin of error will help define the range within which the true mean weight of the tablets is likely to lie.

Ectoplan tablets are a weight gain supplement. They are commonly taken by people who are underweight or who have trouble gaining weight.
The weight of tablets vary. There are many in the 1.2 pound to 1.6 pound range. There are some that weigh more and less than this.
I believe you are asking if you can assume that all tablets in a production run are acceptable if your standard deviation is low. My answer to that is that you can assume they are all acceptable, providing that the tablet press was not stopped during the run and that the granulation was a very good blend with no interruption in the flow of the material to the press.
no
yes
It is an example of continuous variations.
