N Z2 P 1-PC2. Now what Im not sure about is whether I have to determine sample size for each hospital individually using the formula SS Z-score. This expression holds in the case that the population size is infinite in which case the sampling processes can be considered as sampling with replacement.
Sigma σ is provided and the significance level is specified we can compute the minimum required sample size that will lead to a margin of error less than or equal to the one specified by using the following formula.
How many people are you talking about in total.
