Suppose a machine is set to pump gasoline one gallon at a time. The "one gallon" is based on the average of several hundred measurements made during calibration. Assume the measurements varied by chance error, no bias, and the SD of the measurement "population" is estimated to be 0.01 gallons. We buy a sum total of 100 gallons of gasoline. There is about a 95.45% chance we will get within ____ gallons of 100 gallons. What number goes in the blank? Hint: remember, for this purchase, we're adding up 100 gallons, not averaging
