I am studying for my final, and I came across this question.

In a random sample of 583 television viewers, it was found that 65 had watched the tonight show the previous evening.Test the hypotheses that more than 10% of all television viewers watched the tonight show the previous evening.

n= 583
x=65
p-hat=x/n=65/583

H0: p<=10
H1: p>10

I don't know where to go from here. Do I need to find my own alpha?

Thank you very much.
