A survey showed that 35% of human resource professionals are at companies that rejected job candidates because of information found on their social media. If 25 human resource professionals are randomly selected, would 14 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? ... Select the correct choice below and fill in the answer box within your choice. (Round to four decimal places as needed.) O A. No, 14 would not be significantly high because the probability of 14 or more is which is not low. O B. No, 14 would not be significantly high because the probability of 14 or more is , which is low. OC. Yes, 14 would be significantly high because the probability of 14 or more is which is low. O D. Yes, 14 would be significantly high because the probability of 14 or more is which is not low.
