Simple hypothesis testing

Niels has a Magic $8$‍-Ball, which is a toy used for fortune-telling or seeking advice. To consult the ball, you ask the ball a question and shake it. One of $5$‍ different possible answers then appears at random in the ball. Niels sensed that the ball answers "Ask again later" too frequently. He used the ball $10$‍ times and got "Ask again later" $6$‍ times.

Let's test the hypothesis that each answer has an equal chance of $20\mathrm{\%}$‍ of appearing in the Magic $8$‍-Ball versus the alternative that "Ask again later" has a greater probability.

The table below sums up the results of $1000$‍ simulations, each simulating $10$‍ random answers with a $20\mathrm{\%}$‍ chance of getting "Ask again later".

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