He is willing to use \sigma=3 σ = 3 years as an estimate of the standard deviation, and he wants the margin of error to be no more than 1 1 year. Which of these is the smallest approximate sample size required to obtain the desired margin of error? Choose 1 answer:
A smaller margin of error suggests that the survey’s results will tend to be close to the correct values. Conversely, larger MOEs indicate that the survey’s estimates can be further away from the population values. Surveys frequently use random samples to estimate population percentages.
