Unusual Results - Interpreting Statistical Result

A candy company claims that 92% of consumers like their candies. To test this claim, 9571 people are selected at random from those who have eaten the company's candies. 791 rate the candies as unsatisfactory. Is this an unusual result (show criterion for determining the answer to this question)? Also, how do you interpret your statistical result in terms of the company's claim. I need someone to give a mathematical answer. The previous person gave me an explanation, which I could not break down into an equation.
