Math Problem Statement
A survey showed that 34% of human resource professionals are at companies that rejected job candidates because of information found on their social media. If 24 human resource professionals are randomly selected, would 13 be a significantly high number to be at companies that rejected job candidates because of information found on their social media? Why or why not?
