Number of hours your deo lasts (to write on the label)
As an individual seller-that is, not a part of a medium or large company and thus is operating with a limited resources as of yet-
how do you determine how long your deo works (ex, 24h, 48h, 72h), the number of hours you can write on the label if you want to start selling?
Do you have to do a formal, controlled trial with recruited people?
Or is it OK if you just know the rough number based on your sample testing on friends and family if the number of these people is sufficiently large and the effect sufficiently clear to let you know that it is the best guess?
