Question
Alma has developed a new kind of antibiotic that she expects to kill 90% of harmful bacteria when applied.
She applied her antibiotic to a Petri dish full of bacteria, waited for it to take effect, and took a random
sample of 100 bacteria. She found that 84% of them were dead.
Let's test the hypothesis that the actual percentage of dead bacteria is 90% versus the alternative that the
actual percentage is lower than that.
The table below sums up the results of 1000 simulations, each simulating a sample of 100 bacteria,
assuming there are 90% dead bacteria.
According to the simulations, what is the probability of getting a sample with 84% dead bacteria or less?
Let's agree that if the observed outcome has a probability less than 1% under the tested hypothesis, we
will reject the hypothesis.
What should we conclude regarding the hypothesis?
