So she would have had to run an experiment. The most appropriate statistical study, or the most appropriate study would have been a proper controlled experiment where you have a control group where they don't have the antibiotic and a treatment group where they do have the antibiotic. So let's see what are the choices here where they say is the study appropriate. So yes, because she's in a proper study, no, I don't like that answer. No, because she can't know for certain that the true percentage of dead bacteria is above 90%. Well, I'm not gonna click on that because even if she knew for certain that the true percentage of dead bacteria were 95%, she can't feel confident that it was due to the antibiotic. Once again, it could be caused by the air conditioner, could have been caused by the Petri dish, could have been caused by the lighting in the room.
