researchers conducted an experiment to identify the effects of three different hand sanitizer on the growth of bacteria the researchers grew one type of bacteria and 24 identical covered Petri dishes then they open 18 Petri dishes and applied for three hand sanitizers to six Petri dishes Beach they left the remaining six Petri dishes closed as a control when the researchers measure the growth of bacteria 2 Days Later the six dishes that had no hand sanitizer showed the least amount of bacterial growth the researchers concluded that not using any hand sanitizer would lead to the least bacterial growth which statement best explains why the researchers conclusions were not justified

Your question is rather unclear but from what I can tell either there were not an even amount of Petri dishes or some of them were left open while others were not.
