I need help with this problem please. Not too sure on how to interpret and solve it.

In your study, 280 out of 560 cola drinkers prefer Pepsi® over Coca-Cola®. Using these results, test the claim that more than 50% of cola drinkers prefer Pepsi® over Coca-Cola®. Use a = 0.05. Interpret your decision in the context of the original claim. Does the decision support PepsiCo’s claim?
