2. Allana and Brenda are both doing the same experiment, which requires them to use a volumetric pipette (described in the Techniques folder) to dispense a fluid several different times. Allana's results are good and consistent, but Brenda's data vary more than they should from one trial to the next. What are two things Brenda might be doing incorrectly that would cause her this problem? 3. Waylin is doing an experiment that requires an amount of solution to be dispensed by burette. In his notebook's data section, he records that he dispensed 7.5 mL of solution. If you were Waylin's TA, what would you say to him to explain why this is worth no points?

a) Branda is not filling the pipette properly which is leading to the wrong amount of volume transfer at each trial of the experiment.
b) Secondly, the pipette is not getting emptied properly before the start of the experiment, which is leading to the results having huge variations from the old data
