An alien empire is considering taking over planet Earth, but they will only do so if the portion of rebellious humans is less than 10%. They abducted a random sample of 400 humans, performed special psychological tests, and found that 14% of the sample are rebellious Let's test the hypothesis that the actual percentage of rebellious humans is 10% versus the alternative that the actual percentage is higher than that The table below sums up the results of 1000 simulations, each simulating a sample of 400 humans, assuming there are 10% rebellious humans. According to the simulations, what is the probability of getting a sample with 14% rebellious humans or more? 1.5%
2%
0.3%
0.7%

Let's agree that if the observed outcome has a probability less than 1% under the tested hypothesis, we will reject the hypothesis.

We cannot reject the hypothesis
We should reject the hypothesis​
