Question

The size of a sample can be selected by first determining the desired standard error and then using the formula  to calculate n.

Quizplus · Accepted Answer

This statement is true. The formula used to calculate sample size based on desired standard error is typically given as:

n = (Z^2 * s^2) / (E^2)

where:
- n = sample size
- Z = Z-score corresponding to the desired level of confidence
- s = estimated standard deviation of the population
- E = desired margin of error (which is equivalent to the desired standard error, given a particular sample size)
