Dr. Nunez wants to estimate the average lung capacity of adults in her state. She plans on taking a sample of n adults to construct a 99% confidence interval for the mean lung capacity. She wants the margin of error to be no more than 100 mL. She's willing to use o = 300 mL as an estimate for the population standard deviation. Which of these is the smallest approximate sample size required to obtain the desired margin of error?
