Investigator A takes a random sample of 100 men age 18-24 in a community. Investigator B takes a random sample of 1,000 such men.

b. Which investigator will tend to get a bigger standard error of the mean height? Or, can it not be determined?
c. Which investigator is likely to get the tallest man? Or are the chances about the same for both investigators?
