You send a yardstick to a local laboratory for calibration, asking that the procedure be repeated three times. They report the following values:

  1. 35.96 inches
  2. 36.01 inches
  3. 36.03 inches

If you send the yardstick back for a fourth calibration, you would expect to get 36 inches give or take—

  1. .01 inches or so
  2. .03 inches or so
  3. .06 inches or so
