Darren wants to estimate the mean age in a population of trees. He'll sample nnn trees and build a 90\%90%90, percent confidence interval for the mean age. He doesn't want the margin of error to exceed 333 years. Preliminary data suggests that the standard deviation for the ages of trees in this population is \sigma=16σ=16sigma, equals, 16 years. Which of these is the smallest approximate sample size required to obtain the desired margin of error?
