What is formula for calculating sample size of a specific population to obtain a confidence level?
n = [((Za/2)sigma)/E]2
n = sample size
(Za/2) = critical value
sigma = population standard deviation
E = margin of error
This formula can be used when you know sigma and want to determine the necessary sample size to establish, within a confidence of 1-a, the population mean to within +-E.
I won't go into the details of explaining it, because the site I myself am reviewing from right now has an excellent explanation, and I strongly suggest reading through it. Visit it here.

Who devised the formula for calculating sample size in a survey?
The formula for calculating sample size in a survey has been developed and refined by various statisticians over time, with significant contributions from figures such as Jerzy Neyman and Ronald A. Fisher. Neyman's work in the 1930s laid the foundation for modern sample size determination, emphasizing the importance of margin of error and confidence levels. The basic formula considers population size, desired confidence level, margin of error, and variability within the population. Today, many variations of the formula exist, tailored to specific research needs and contexts.
What is the formula for calculating population density -?

What is the formula for calculating force vs displacement?
The formula for calculating force vs displacement depends on the specific situation. In general, the formula is force = k * x where k is the spring constant and x is the displacement from the equilibrium position. For different situations, such as friction or gravity, additional factors may need to be included in the formula.
