Which of the following is not required to determine minimum sample size to estimate a population​ mean?

Question: Which of the following is not required to determine minimum sample size to estimate a population​ mean?

A. The desired confidence level

B. The desired margin of error

C. The size of the​ population, N

D. The value of the population standard​ deviation, sigma

C. The size of the population, N, is not required to determine the minimum sample size to estimate a population mean. The minimum sample size can be determined using the desired confidence level, the desired margin of error, and the population standard deviation (if known) or the sample standard deviation (if unknown). The size of the population does not affect the calculation of the minimum sample size, but it can affect the selection of the appropriate sampling method and the accuracy of the estimate. However, if the population size is very large (e.g. greater than 100,000), it may be necessary to use a correction factor when calculating the sample size.
