Question

In an experiment, petri dishes of bacteria are set up and an antibiotic that routinely kills 90–100% of the bacteria is applied. An entire biology class does this experiment, with each student having five petri dishes. The data is shown to match the effectiveness that the antibiotic describes. Table 1: Average number of bacteria counted on 5 plates without the antibiotic and 5 plates with the antibiotic. Student Control Average Petri Dish Average A 100 8 B 83 4 C 92 2 Which of these terms describe the data? Check all that apply. precise accurate and reproducible replicated but not repeated repeated accurate but not reproducible
