Formula To Find Sample Size. If we are using three independent variables then a clear rule would be to have a minimum sample size of 30. Here take confidence level as 99 and confidence interval as 001.
The formula does not cover finite population. Determine the confidence level. Find the sample size for some finite and infinite population when the percentage of 4300 population is given as 005.
If the population is N then the corrected sample size should be 186N N185.
Determine the confidence level. The formula does not cover finite population. N population size e Margin of error percentage in decimal form z z-score The z-score is the number of standard deviations a given proportion is away from the mean. Determine the confidence interval.
