From your current data for the interval (all thirty points), you have a certain percentage uncertainty for the average that would be (o/x)-100%. If you wanted to reduce the percentage uncertainty by 1/3, how many measurements would you need to take? Show all of your calculations. The results will indicate why good survey data in politics, medical trials, marketing, et cetera can be very expensive.
