hypothesis testing question for s1

Mrs da Silva is running for president. She claims to have 60% of the population supporting her.

She is suspected of overestimating her support and a random sample of 20 people are asked whom they support. Only nine day mrs da Silva.

Test, at the 5% significance level, the hypothesis that she has overestimated her support.

By the way you may need to look at Cumulative binomial probability tables

You know using the information, that it's going to be X B(20,0.60) X ~ B(20, 0.60)

What do you think H0 H_0 and H1 H_1 are?
