Associations A through E are sponsoring a certain professional conference. Each of the attendees of this conference is a member of at least two of these sponsoring organizations. On the conference registration form, each attendee indicated which of these associations he or she considers to be primary and which he or she considers to be secondary. No attendee listed the same association as both primary and secondary. The graph shows these registration results for the 80 attendees.
Select from each drop-down menu the option that creates the most accurate statement about the attendees of this conference.
Association is more than twice as likely to be listed as a randomly selected attendee’s secondary association than as the attendee's primary association.
Of the five associations, Association is most likely to be among a randomly selected attendee's associations (primary or secondary).
We have 80 attendees, if an attendee is chosen/selected randomnly, the association that was considered as either his primary choice or the secondary choice, the probability of it being Association A is higher, as it is considered as a primary by 34 attendees and secondary by 26. 34+26=60 the probability is higher clearly which is not the case for others. In case of B, its considered Primary by 26 attendees and secondary by 27 attendees, 26+27 = 53.
