Charlotte is left-handed. She heard that about of all people are left-handed, but she suspected that the percentage of lefties in her school is greater. She took a random sample of students, and found that of them are left-handed. Let's test the hypothesis that the actual percentage of left-handed students is versus the alternative that the actual percentage is higher than that. The table below sums up the results of simulations, each simulating a sample of students, assuming there are left-handed students. According to the simulations, what is the probability of getting a sample with left-handed students or more? Let's agree that if the observed outcome has a probability less than under the tested hypothesis, we will reject the hypothesis.
