e. Both deliveries were intended to deliver "4 mL". For both the pipet and graduated cylinder, determine how many significant figures should be used to express the value appropriately, should the volume be expressed as "4 mL", "4.0 mL", "4.00 mL", "4.000 mL", "4.0000 mL", etc.? Key: Which digit is the first uncertain digit? i. Select the number of significant figures for the graduated cylinder. ii. Select the number of significant figures for the pipet.

Select the answer that best cites your data and/or calculations as evidence.
- My results agree - my absolute error and standard deviation were less than the claimed values
- My results somewhat agree - my absolute error was less than the claimed value, but my standard deviation was greater than the claimed precision
- My results somewhat agree - my standard deviation was less than the claimed value, but my absolute error was greater than the claimed accuracy.
- My results don't agree at all - both my absolute error and standard deviation were greater than the claimed values.
