# Andrew took a random sample of 10 decorated ceramic cups from a population of 100 cups. barbara took another random sample of 10 cups from the same population for the same task. what would happen if andrew and barbara both choose a sample size of 20? the difference of their sample means is likely to .. a. remain the same b. increase c. decrease

i think the answer is increase because:

10 divide by 100 = 0.1

10 divided by 90 = 0.1

but 20 divided by 100 = 0.2

and 20 divided by 80= 0.25
