Determine The Minimum Sample Size Required. The formula does not cover finite population. Assume the population is normally distributed.
For a test with 005 and 010 the minimum sample size required for the test is More often we must compute the sample size with the population standard deviation being unknown The procedures for computing sample sizes when the standard deviation is not known are similar to but more complex than when the standard deviation is known. Determine the minimum sample size required when you want to be 90 confident that the sample mean is within one unit of the population mean and o 126. The formula does not cover finite population.
Consider your sample size variables 1.
Errors are inevitable the question is how much error youll allow. Determine the minimum sample size required when you want to be 90 confident that the sample mean is within one unit of the population mean and o 126. How many people are you talking about in total.
