Simple hypothesis testing

Angela is left-handed. She heard that about 12%12\% 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 5050 students, and found that 20%20\% of them are left-handed.
Let's test the hypothesis that the actual percentage of left-handed students is 12%12\% versus the alternative that the actual percentage is higher than that.
The table below sums up the results of 10001000 simulations, each simulating a sample of 5050 students, assuming there are 12%12\% left-handed students.
According to the simulations, what is the probability of getting a sample with 20%20\% left-handed students or more?
Let's agree that if the observed outcome has a probability less than 1%1\% under the tested hypothesis, we will reject the hypothesis.
What should we conclude regarding the hypothesis?
