You can use the binomial distribution to perform a hypothesis test if the conditions for a binomially distributed event are met:

• there is a fixed number of trials (n),
• there are only two possible outcomes (success and failure),
• there is a fixed probability of success (p), and
• the trials are independent of each other.

To perform the test:

• Define the test statistic
• Determine whether a one-tailed or two-tailed test is needed
• Identify the null and alternate hypotheses accordingly
• Calculate the probability of the test statistic taking the observed value or higher/lower, assuming the null hypothesis to be true
• Compare this to the significance level, and either reject or cannot reject the null hypothesis
• Conclude with a statement in context of the question
