When a calculated sample size must be adjusted due to the size of the population relative to the size of the sample,which of the following formulas should be applied?
A) Divide the calculated n by the standard error of the mean
B) Multiply the calculated n by the precision estimate
C) Reduce the calculated n by 5% of the population size
D) Multiply the calculated n by the square root of (N - n)/(N - 1)
E) Divide the calculated n by the standard deviation squared

The formula to adjust the sample size due to the size of the population relative to the size of the sample is to multiply the calculated n by the square root of (N - n)/(N - 1). This will give a more accurate representation of the population with a larger sample size.
