Stats ANOVA versus Chi Square Testing!

Hi everyone.
Try working this question that's been bogging me down from the Kaplan books if you will. They asked which scales method would be best (?simplest) for the following requirement.
A doctor believes that drawing blood is faster with a vacutainer for someone once that person is trained, but faster with a standard syringe for someone with no training.
Kaplan’s book says this needs to be done with a One-way ANOVA. Can’t this be done with a Chi square using on the X-axis ‘Trained’ and ‘Untrained’, and on the Y-axis, ‘Faster with a Vacutainer’ and ‘Faster with a conventional syringe’?
Thanks

You are supposed to take time(speed) also into consideration."faster" or "slower" i.e speed is the third variable.
